I am working on an issue where i need to Declare a two - dimensional array named multiplicationTable
that contains 4 elements by 4 elements.Initialize it in
a nested loop to contain elements that equal to the value
that is the product of the two index values for
each element. In a second nested loop, display the values
in the console output, with column elements separated with
commas, and row elements separated with carriage returns. This is what i have so far, for some reason can't wrap my brain around the solution! Any help would be appreciated!.
double[,] multiplicationTable = new double[4, 4];// { {1,2,3,4 }, {5,6,7,8 }, {9,10,11,12 }, {13,14,15,16 } };
for (int i = 0; i < multiplicationTable.GetLength(0); i++)
{
for (int j = 0; j < multiplicationTable.GetLength(1); j++)
{
double d = multiplicationTable[i, j];
if (j < multiplicationTable.GetLength(1) - 1)
{
Console.Write(d + ",");
}
else
{
Console.Write(d);
}
}
Console.Write("\n");
}
Console.ReadKey();
double[,] multiplicationTable = new double[4, 4];
for (int i = 0; i < multiplicationTable.GetLength(0); i++)
{
for (int j = 0; j < multiplicationTable.GetLength(1); j++)
{
multiplicationTable[i, j] = i * j;
double d = multiplicationTable[i, j];
if (j < multiplicationTable.GetLength(1) - 1)
{
Console.Write(d + ",");
}
else
{
Console.Write(d);
}
}
Console.Write("\n");
}
Console.ReadKey();
Why not try to solve this with String.Join method? It is easy to use and will save you a lot of if-else statements. Here it is how it will look like with this method:
double[,] multiplicationTable = new double[4, 4] { { 1, 2, 3, 4 }, { 5, 6, 7, 8 }, { 9, 10, 11, 12 }, { 13, 14, 15, 16 } };
for (int i = 0; i < multiplicationTable.GetLength(0); i++)
{
var temp = new string[4];
for (int j = 0; j < multiplicationTable.GetLength(1); j++)
{
temp[j] = multiplicationTable[i, j].ToString();
}
Console.WriteLine(string.Join(",", temp));
}
Console.ReadKey();
double[,] multiplicationTable = new double[4, 4];
for (int i = 0; i < multiplicationTable.GetLength(0); i++)
{
var temp = new string[multiplicationTable.GetLength(0)];
for (int j = 0; j < multiplicationTable.GetLength(1); j++)
{
multiplicationTable[i, j] = i * j;
temp[j] = multiplicationTable[i, j].ToString();
}
Console.WriteLine(string.Join(",", temp));
}
I have been given this task to solve:
Write a program that reads an array of integers and removes from it a minimal number of elements in such a way that the remaining array is sorted in increasing order. Print the minimal number of elements that need to be removed in order for the array to become sorted.
Time limit 0.1sec.
Sample test:
Input:
1,
4,
3,
3,
6,
3,
2,
3
Output:
3
Unfortunately, my program is slower. This is my code:
using System;
static bool CheckAscending(List<int> list)
{
bool ascending = true;
for (int i = 0; i < list.Count - 1; i++)
{
if (list[i] > list[i + 1])
{
ascending = false;
}
}
return ascending;
}
static void Main()
{
int n;
n = int.Parse(Console.ReadLine());
List<int> arr = new List<int>();
List<int> sorted = new List<int>();
int maxSubsetLenght = 0;
for (int i = 0; i < n; i++)
{
arr.Add(int.Parse(Console.ReadLine()));
}
for (int i = 1; i <= (int)Math.Pow(2, n) - 1; i++)
{
int tempSubsetLenght = 0;
List<int> temp = new List<int>();
for (int j = 1; j <= n; j++)
{
if (((i >> (j - 1)) & 1) == 1)
{
temp.Add(arr[j - 1]);
tempSubsetLenght++;
}
}
if ((tempSubsetLenght > maxSubsetLenght) && (CheckAscending(temp)))
{
sorted = temp;
maxSubsetLenght = tempSubsetLenght;
}
}
Console.WriteLine(n - sorted.Count);
}
Can someone help me to make my program a bit faster. I will be glad if you could answer in the near future.
Ok I found how to soleve it and thanks #Gabor for your help :). Here is my solution:
using System;
static void Main(string[] args)
{
int n = int.Parse(Console.ReadLine());
List<int> numbers = new List<int>();
for (int i = 0; i < n; i++)
{
int currentNumber = int.Parse(Console.ReadLine());
numbers.Add(currentNumber);
}
int[] size = new int[numbers.Count];
// Define each number as subsequence.
for (int i = 0; i < numbers.Count; i++)
{
size[i] = 1;
}
int max = 1;
// Compare current number with the numbers before.
for (int i = 1; i < numbers.Count; i++)
{
for (int j = 0; j < i; j++)
{
if (numbers[i] >= numbers[j] && size[i] <= size[j] + 1)
{
size[i] = size[j] + 1;
// Update max increasing subsequence.
if (max < size[i])
{
max = size[i];
}
}
}
}
// Print numbers to remove as a result.
int numbersToRemove = n - max;
Console.WriteLine(numbersToRemove);
}
I think it would be helpful for other people, who have the same task to do like me.
UPDATE #2
When there is a decrease then we should delete not only the current number but all the numbers before which are more than the new minValue.
The Stopwatch is in the System.Diagnostic namespace.
// int?[] numbers = new int?[] { 8, 1, 4, 3, 3, 6, 3, 2, 3 };
int?[] numbers = new int?[] { -7, -7, -7, -100, -100, -99, 4, -90, -80, -70 };
Console.WriteLine("Array: [{0}]", String.Join(", ", numbers));
System.Diagnostics.Stopwatch watch = new Stopwatch();
watch.Start();
int minValue = Int32.MinValue;
for (int i = 0; i < numbers.Length - 1; i++)
{
var currentNumber = numbers[i];
var nextNumber = numbers[i + 1];
if (currentNumber > nextNumber)
{
if (nextNumber < minValue)
{
numbers[i + 1] = null;
}
else
{
minValue = nextNumber.Value;
for (int j = i; j >= 0; j--)
{
if (numbers[j] > minValue)
{
numbers[j] = null;
}
}
}
}
}
watch.Stop();
Console.WriteLine("Result: {0}; Time: {1} ms", numbers.Count(number => number == null), watch.ElapsedMilliseconds);
Console.WriteLine("Array: [{0}]", String.Join(", ", numbers));
I couldn't get it to work, I am trying to arrange the values of the array in ascending order by using for loop.
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
for (int i = 0; i <= arr.Length; i++)
{
if (arr[i] > arr[i + 1])
{
int temp = arr[i + 1];
arr[i] = arr[i + 1];
arr[i] = temp;
}
Console.Write(arr[i]);
}
I am assuming that you are not using Array.Sort because you are doing this as a learning exercise; there is no other way to avoid this very common library function.
The reason your algorithm does not work is that it is not enough to go through an array once, and swap items that are out of order. Try doing this as a mental experiment, when the array is almost sorted, but the first element is at the end, like this:
2 3 4 5 6 7 1
A single path would bring you closer, but it wouldn't bring you all the way to a sorted array:
2 3 4 5 6 1 7
As you can see, you have to repeat this process multiple times, until the array is sorted. How do you know that the array is sorted? You know that when the entire inner loop did not have a single swap.
Here is how you can implement this:
bool didSwap;
do {
didSwap = false;
for (int i = 0; i < arr.Length-1; i++)
{
if (arr[i] > arr[i + 1])
{
int temp = arr[i + 1];
arr[i + 1] = arr[i];
arr[i] = temp;
didSwap = true;
}
}
} while (didSwap);
for (int i = 0; i != arr.Length ; i++) {
Console.Write(arr[i]);
}
Note several changes from your code:
The printing is done in the separate loop, after the sorting is complete
The loop goes to arr.length-1, not to arr.length, because otherwise your last check will go outside the bounds of the array.
This sorting algorithm is called Bubble Sort. There are various optimizations to this algorithm that can make it go slightly faster.
In general, bubble sort is among the slower sorting algorithms. When the number of items to sort is high, you should consider an advanced algorithm, or use the library implementation.
int[] Array = { 11, 33, 5, -3, 19, 8, 49 };
int temp;
for (int i = 0; i < Array.Length - 1; i++)
{
for (int j = i + 1; j < Array.Length; j++)
{
if (Array[i] > Array[j])
{
temp = Array[i];
Array[i] = Array[j];
Array[j] = temp;
}
}
}
Console.Write("Sorted:");
foreach (int sort in Array)
Console.Write("{0} ", sort);
If you want to make your own sorting, then it's not enough to just loop through the items once and swap them. The closest to that is the bubble sort algorithm, where you loop over the array repeatedly until there is no more items to swap:
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
bool swapped = true;
while (swapped) {
swapped = false;
for (int i = 0; i < arr.Length - 1; i++) {
if (arr[i] > arr[i + 1]) {
swapped = true;
int temp = arr[i + 1];
arr[i] = arr[i + 1];
arr[i] = temp;
}
}
}
for (int i = 0; i < arr.Length - 1; i++) {
Console.Write(arr[i]);
}
There are also built in methods to sort data, which is easier to use, more efficient, and already thoroughly tested:
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
Array.Sort(arr);
Use Linq Order by:
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
int[] ascOrderedArray = (from i in arr orderby i ascending select i).ToArray();
I think it could be easy and why do you need for loop.

You should do like :
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
for (int i = 0; i < arr.Length-1; i++)
{
if (arr[i] < arr[i + 1])
{
int temp = arr[i];
arr[i] = arr[i + 1];
arr[i + 1] = temp;
}
}
// to verify sorted Array
for (int i = 0; i < arr.Length; i++)
{
console.write( arr[i].ToString());
}
For last 1 you need not to check it will be automatically ordered.
#Jon Skeet They wanted to use a for loop.
There are numerous types of sorts. The simplest is Bubble Sort.
int[] arr = new int[5] { 5, 6, 2, 4, 1 };
//bubble sort
for (int i = arr.Length - 1; i > 0; i--)
{
for (int j = 0; j <= i - 1; j++)
{
if (arr[j] > arr[j + 1])
{
int highValue = arr[j];
arr[j] = arr[j + 1];
arr[j + 1] = highValue;
}
}
}
foreach(int i in arr) Console.Write(i);
I was just asking if there is a simple way of doing this.
i.e. Replacing two consecutive cell with one cell having different value.
For ex: - if my array =[0,3,1,2,3,4], and i want to replace index 0,and 1 with the value 5
to become like this array=[5,1,2,3,4]
Can you guys suggest some simple way for doing this.
i do this code but there is something wrong:
int J = 0;
if (max != 1)
{
for (int iii = 0; iii < output.Length -1; iii++)
{
if ((output[iii] == imax) && (output[iii + 1] == jmax))
{
temp = temp + 1;
output[J] = Convert.ToByte(temp);
J = J + 1;
iii = iii + 1;
}
else
{
output[J] = output[iii];
J = J + 1;
output[J] = output[iii + 1];
}
}
}
because when i want to check the 2 consecutive index ,i want to pass them to the anther 2 index
If you care about performance you want to do as little operations that can harm performance. Try this extension method:
public static int[] ReplaceConsecutiveCells(this int[] array, int startIndex, int replaceWith)
{
int[] targetArray = new int[array.Length - 1];
for (int i = 0; i < array.Length; i++)
{
if (i < startIndex)
{
targetArray[i] = array[i];
}
else if (i == startIndex)
{
targetArray[i] = replaceWith;
}
else if (i == startIndex + 1)
{
// no action
}
else
{
targetArray[i - 1] = array[i];
}
}
return targetArray;
}
Use it like this:
array = array.ReplaceConsecutiveCells(0, 5);
int[] array = new int[] { 0, 3, 1, 2, 3, 4 };
List<int> list = array.ToList();
list.RemoveRange(0,2);
list.Insert(0, 5);
array = list.ToArray();
Yet another variant
int[] array = new int[] { 0, 3, 1, 2, 3, 4 };
Array.Reverse(array);
Array.Resize(ref array, 5);
Array.Reverse(array);
array[0] = 5;
do
{
RNG_NXT =RNG +1;
for (int iii = 0; iii <Nold -1; iii++)
{
if ((output[iii] == imax) && (output[iii + 1] == jmax))
{
output[J] = Convert.ToByte(RNG_NXT);
J = J + 1;
iii = iii + 1;
}
else
{
output[J] = output[iii];
J = J + 1;
}
}
RNG++;
}
while( RNG < RNG_MAX) ;
int[] arr = {800,11,50,771,649,770,240, 9};
int temp = 0;
for (int write = 0; write < arr.Length; write++)
{
for (int sort = 0; sort < arr.Length - 1; sort++)
{
if (arr[sort] > arr[sort + 1])
{
temp = arr[sort + 1];
arr[sort + 1] = arr[sort];
arr[sort] = temp;
}
}
Console.Write("{0} ", arr[write]);
}
All I am attempting to do is a simple bubble sort with this array. I would like to figure out why the sorting is screwed up.
In example, here is when the array is {800,11,50,771,649,770,240, 9}:
Here is what gets displayed: 11, 50, 649, 9, 649, 770, 771, 800
I am thinking that I might be missing something in the comparison.
No, your algorithm works but your Write operation is misplaced within the outer loop.
int[] arr = { 800, 11, 50, 771, 649, 770, 240, 9 };
int temp = 0;
for (int write = 0; write < arr.Length; write++) {
for (int sort = 0; sort < arr.Length - 1; sort++) {
if (arr[sort] > arr[sort + 1]) {
temp = arr[sort + 1];
arr[sort + 1] = arr[sort];
arr[sort] = temp;
}
}
}
for (int i = 0; i < arr.Length; i++)
Console.Write(arr[i] + " ");
Console.ReadKey();
This one works for me
public static int[] SortArray(int[] array)
{
int length = array.Length;
int temp = array[0];
for (int i = 0; i < length; i++)
{
for (int j = i+1; j < length; j++)
{
if (array[i] > array[j])
{
temp = array[i];
array[i] = array[j];
array[j] = temp;
}
}
}
return array;
}
public static void BubbleSort(int[] a)
{
for (int i = 1; i <= a.Length - 1; ++i)
for (int j = 0; j < a.Length - i; ++j)
if (a[j] > a[j + 1])
Swap(ref a[j], ref a[j + 1]);
}
public static void Swap(ref int x, ref int y)
{
int temp = x;
x = y;
y = temp;
}
int[] arr = { 800, 11, 50, 771, 649, 770, 240, 9 };
int temp = 0;
for (int write = 0; write < arr.Length; write++)
{
for (int sort = 0; sort < arr.Length - 1 - write ; sort++)
{
if (arr[sort] > arr[sort + 1])
{
temp = arr[sort + 1];
arr[sort + 1] = arr[sort];
arr[sort] = temp;
}
}
}
for (int i = 0; i < arr.Length; i++) Console.Write(arr[i] + " ");
Console.ReadKey();
I saw someone use this example as part of a job application test. My feedback to him was that it lacks an escape from the outer loop when the array is mostly sorted.
consider what would happen in this case:
int[] arr = {1,2,3,4,5,6,7,8};
here's something that makes more sense:
int[] arr = {1,2,3,4,5,6,7,8};
int temp = 0;
int loopCount=0;
bool doBreak=true;
for (int write = 0; write < arr.Length; write++)
{
doBreak=true;
for (int sort = 0; sort < arr.Length - 1; sort++)
{
if (arr[sort] > arr[sort + 1])
{
temp = arr[sort + 1];
arr[sort + 1] = arr[sort];
arr[sort] = temp;
doBreak=false;
}
loopCount++;
}
if(doBreak){ break; /*early escape*/ }
}
Console.WriteLine(loopCount);
for (int i = 0; i < arr.Length; i++) Console.Write(arr[i] + " ");
public static int[] BubbleSort(int[] arr)
{
int length = arr.Length();
while (length > 0)
{
int newLength = 0;
for (int i = 1; i < length; i++)
{
if (arr[i - 1] > arr[i])
{
Swap(ref arr[i - 1], ref arr[i]);
newLength = i;
}
}
length = newLength;
}
}
public static void Swap(ref int x, ref int y)
{
int temp = y;
y = x;
x = temp;
}
I wanted to add to the accepted answer something different:
Number of iterations can be reduced as well, as below.
int[] arr = { 800, 11, 50, 771, 649, 770, 240, 9 };
int temp = 0;
int arrLength = arr.Length;
for (int write = 0; write < arr.Length - 1; write++, arrLength--)
{
for (int sort = 0; sort < arrLength - 1; sort++)
{
if (arr[sort] > arr[sort + 1])
{
temp = arr[sort + 1];
arr[sort + 1] = arr[sort];
arr[sort] = temp;
}
}
}
foreach (var item in arr)
{
Console.WriteLine(item);
}
Your Console.Write("{0} ", arr[write]); is too early. You're printing the values while the sort is still in progress. For example, you're printing 9 as being index 3 in the array, yet on the very next iteration of the loop the 9 has moved to index 2 and 240 has moved to index 3... yet you're outer loop has moved forward so it prints 649 the second time and 240 never gets printed.
int[] array = new int[10] { 13, 2, 5, 8, 23, 90, 41, 4, 77, 61 };
for (int i = 10; i > 0; i--)
{
for (int j = 0; j < 9; j++)
{
if (array[j] > array[j + 1])
{
int temp = array[j];
array[j] = array[j + 1];
array[j + 1] = temp;
}
}
}
static bool BubbleSort(ref List<int> myList, int number)
{
if (number == 1)
return true;
for (int i = 0; i < number; i++)
{
if ((i + 1 < number) && (myList[i] > myList[i + 1]))
{
int temp = myList[i];
myList[i] = myList[i + 1];
myList[i + 1] = temp;
}
else
continue;
}
return BubbleSort(ref myList, number - 1);
}
Just another example but with an outter WHILE loop instead of a FOR:
public static void Bubble()
{
int[] data = { 5, 4, 3, 2, 1 };
bool newLoopNeeded = false;
int temp;
int loop = 0;
while (!newLoopNeeded)
{
newLoopNeeded = true;
for (int i = 0; i < data.Length - 1; i++)
{
if (data[i + 1] < data[i])
{
temp = data[i];
data[i] = data[i + 1];
data[i + 1] = temp;
newLoopNeeded = false;
}
loop++;
}
}
}
Bubble sort with sort direction -
using System;
public class Program
{
public static void Main(string[] args)
{
var input = new[] { 800, 11, 50, 771, 649, 770, 240, 9 };
BubbleSort(input);
Array.ForEach(input, Console.WriteLine);
Console.ReadKey();
}
public enum Direction
{
Ascending = 0,
Descending
}
public static void BubbleSort(int[] input, Direction direction = Direction.Ascending)
{
bool swapped;
var length = input.Length;
do
{
swapped = false;
for (var index = 0; index < length - 1; index++)
{
var needSwap = direction == Direction.Ascending ? input[index] > input[index + 1] : input[index] < input[index + 1];
if (needSwap)
{
var temp = input[index];
input[index] = input[index + 1];
input[index + 1] = temp;
swapped = true;
}
}
} while (swapped);
}
}
This is what I wrote using recursive methods:
public static int[] BubbleSort(int[] input)
{
bool isSorted = true;
for (int i = 0; i < input.Length; i++)
{
if (i != input.Length - 1 && input[i] > input[i + 1])
{
isSorted = false;
int temp = input[i];
input[i] = input[i + 1];
input[i + 1] = temp;
}
}
return isSorted ? input : BubbleSort(input);
}
It does the same in a more elegant way.
var arrayValues = new[] { 99, 12, 11, 300, 400, 10, 9, 3, 6, 5, 7, 8};
for (var mainLoop = 0; mainLoop < arrayValues.Length; mainLoop++)
{
for (var innerLoop = mainLoop + 1; innerLoop < arrayValues.Length; innerLoop++)
{
if (arrayValues[mainLoop] <= arrayValues[innerLoop])
{
continue;
}
var temp = arrayValues[mainLoop];
arrayValues[mainLoop] = arrayValues[innerLoop];
arrayValues[innerLoop] = temp;
}
}
So i did mine as a recursive function (no need for the nested loop), perhaps someone could comment if this is inefficient (when compared to the other solutions).
public static int[] BubbleSort(int[] arrayOfValues)
{
var swapOccurred = false;
for (var i = 0; i < arrayOfValues.Length; i++)
{
if (i == arrayOfValues.Length - 1)
continue;
if (arrayOfValues[i] > arrayOfValues[i + 1])
{
//swap values
var current = arrayOfValues[i];
var next = arrayOfValues[i + 1];
arrayOfValues[i] = next;
arrayOfValues[i + 1] = current;
swapOccurred = true;
}
}
if (swapOccurred)
{
// keep going until no further swaps are required:
BubbleSort(arrayOfValues);
}
return arrayOfValues;
