I am currently writing a program dealing with Cartesian Product. I have figured out the first part of inputting two numbers and getting the set for each number inputted. But what i need is the final product of both numbers.
In other words I am looking for my product to look something like this:
{ (1,1), (1,2), (1,3), ... }
Here is my code for right now with the last part of where I need help.
private void btnCal_Click(object sender, EventArgs e)
{
int iN, iM, i, j;
string strOut1, strOut2, strOut;
bool bN, bM;
bN = int.TryParse(txtN.Text, out iN);
bM = int.TryParse(txtM.Text, out iM);
if (bN && bM && iM > 0 && iM > 0)
{
strOut1 = "{1";
for (i = 2; i <= iM; i++)
strOut1 += "," + i;
txtFirst.Text = strOut1 + "}";
strOut2 = "{1";
for (j = 2; j <= iN; j++)
strOut2 += "," + j;
txtSecond.Text = strOut2 + "}";
}
//HERE IS WHERE THE PRODUCT CODE WILL BE AT
if (bN && bM && iM > 0 && iM > 0)
{
for (i = 2; i <= iM; i++)
for (j = 2; j <= iN; j++)
strOut = ("strOut1");
txtProduct.Text = strOut + " }";
}
else
txtProduct.Text = "Please enter valid number.";
}
With LINQ, all things are possible:
using System;
using System.Linq;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnCal_Click(object sender, EventArgs e)
{
var tuples = from m in Enumerable.Range(1, int.Parse(txtM.Text))
from n in Enumerable.Range(1, int.Parse(txtN.Text))
select Tuple.Create(m, n);
txtProduct.Text = "{" + String.Join(",", tuples) + "}";
}
}
}

Using Visual Studio C# ASP.NET I need to calculate how many letters 'u' does each path has.
Input :
zzzzzzzzzuzuzzz
uuzuuzuuzuuuzzz
zuzuzzuzuuzuzuz
zuzuzzuzzuzuuuz
zuuuuuuuzuzzzzz
zzzzzuuuzzzzzzz
Picture of the map and given data for better quality
Output :

I have this code right now.
It finds the paths (there's 2 total), but now I need to find how many letters 'u' does each path has.
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string path = "App_Data/Map.txt";
string[] lines = File.ReadAllLines(HttpContext.Current.Server.MapPath(path));
int Width = int.Parse(lines[0]);
int Height = int.Parse(lines[1]);
Label4.Text = "Width: " + Width.ToString();
Label5.Text = "Height: " + Height.ToString();
}
protected void Button1_Click(object sender, EventArgs e)
{
string path = "App_Data/Map.txt";
string map = File.ReadAllText(HttpContext.Current.Server.MapPath(path));
char[][] grid = GetGridGFromMap(map);
int NumberOfMoles = TaskUtils.LettersIsU(grid);
Label1.Text = "Letters U count: " + NumberOfMoles.ToString();
}
private char[][] GetGridGFromMap(string map)
{
string[] lines = map.Split('\n');
char[][] grid = new char[lines.Length][];
for(int i =0; i < lines.Length; i++)
{
grid[i] = lines[i].ToCharArray();
}
return grid;
}
}
class TaskUtils
{
public static int LettersIsU(char[][] grid)
{
int count = 0;
for (int i = 0; i < grid.Length; i++)
{
for (int j = 0; j < grid[i].Length; j++)
{
if (grid[i][j] == 'u')
{
count++;
SetCountedLetters(grid, i, j);
}
}
}
return count;
}
private static void SetCountedLetters(char[][] grid, int i, int j)
{
if (i < 0 || i >= grid.Length || j < 0 || j >= grid[i].Length || grid[i][j] == 'z')
return;
grid[i][j] = 'z';
SetCountedLetters(grid, i + 1, j);
SetCountedLetters(grid, i - 1, j);
SetCountedLetters(grid, i, j + 1);
SetCountedLetters(grid, i, j - 1);
}
}
}
Here's my code.
CustomClass.cs
class ScoreBoard(){
private int m_lastCnt;
public ScoreBoard{
m_lastCnt = 0;
}
public void makeBoard(string history) {
string[] arrPartStr = history.Split(',');
int[] arrPart = new int[arrPartStr.Length];
for (int c = 0; c < arrPart.Length; c++)
{
int temp = 0;
if (arrPartStr[c][0] == 'P') temp = 100;
else if (arrPartStr[c][0] == 'B') temp = 200;
else temp = 300;
if (arrPartStr[c][1] == 'P') temp += 10;
if (arrPartStr[c][2] == 'P') temp += 1;
arrPart[c] = temp;
}
//var strTmp : String = strData;
//strTmp = "311|101|211|211|211|211|211|211|211|211|111|111|111|111|111|111|111|111|111"
//strTmp = strData.replace(/:/g,"");
int[,] arrTmp = new int[6100, 104];
}
}
Main Class i call the void method like this
ScoreBoard sb = ScoreBoard();
string history = "s ,o ,m ,e ,s ,t ,r ,i ,n ,g";
private void Start(){
sb.makeBoard(history);
}
How can i print my 2D array in my console?
I tried doing it like the for(int row){for(int col){}} but its not working i don't know why
Do you mean this?
for (int j = 0; j < arrTmp.GetLength(1); j++)
{
for (int i = 0; i < arrTmp.GetLength(0); i++)
{
var msg = "[" + i.ToString() + ", " + j.ToString() + "] = " + arrTmp[i, j].ToString();
Debug.Log(msg);
}
}
I got it to display:)
CustomClass.cs
int[,] arrTmp = new int[104, 6];
public int[,] GetBoard(){ return arrTmp }
MainClass.cs
int[,] arrayBigRoad = bsb.GetBoard();
for (int j = 0; j < arrTmp.GetLength(1); j++)
{
for (int i = 0; i < arrTmp.GetLength(0); i++)
{
var msg = "[" + i.ToString() + ", " + j.ToString() + "] = " + arrTmp[i, j].ToString();
Debug.Log(msg);
}
}
Thanks though Rodrigo . I'll mark yours as an answer
i have made textbox 1 and 2 to create a row of x's starting with one x, then enter and then xx and so on..
now i need textbox 3 and 4 to display the same but it has to do it beginning from 10 x's.
this is what i have:
namespace Vierkant
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void button_Click_1(object sender, RoutedEventArgs e)
{
string x = "X";
for (int i = 0; i < 10; i++)
{
if ( i == 0)
{
x = "X";
}
else
{
x += "X";
}
txt_box1.Text += (x) + "\n";
txt_box2.Text += (x) + "\n";
}
for (int j = 10; j > 0; j--)
{
if (j == 10)
{
x = x.Remove(x.Length - 1);
}
else
{
x = x.Remove(x.Length - 1);
}
txt_box3.Text += (x) + "\n";
txt_box4.Text += (x) + "\n";
// txt_box4.Text displays correct but starts from 9 x's?
}
}
}
}
You are removing one of the x's before displaying it.
if (j == 10)
{
x = x.Remove(x.Length - 1);
}
Perhaps a better solution would be:
if (j < 10)
{
x = x.Remove(x.Length - 1);
}
Try with this:
private void button_Click_1(object sender, RoutedEventArgs e)
{
int i;
string allLines = "";
for (i = 1; i <= 10; i++)
allLines += new string('X', i) + (i < 10 ? "\n" : "");
txt_box1.Text = allLines;
txt_box2.Text = allLines;
allLines = "";
while (--i > 0)
allLines += new string('X', i) + (i > 1 ? "\n" : "");
txt_box3.Text = allLines;
txt_box4.Text = allLines;
}
This way is much clearer and more efficient, you are creating MUCH LESS strings in memory.
I'm working on visual C#
to calculate the word error rate
I have one textbox for the refrence which is the correct sentance
and one for the hypothesis which is wrong one.
in order to calculate WER I need to calculate :
substitution : the word that has been changed which was my first question
Insert : the words that had been inserted in the sentence
Deleted: the words that had been deleted from the original sentence
For EX:
refrence: This is a NPL program.
hypothesis: it is an NPL cool.
it: substitution
is: correct
an :substitution
NPL:correct
program: deleted
cool: inserted
I tried the algorithm that dasblinkenlight proposed ( thank you so much by the way )
I worked but there is a runtime error I couldn't figure it out, in line

can you help me please ?
There is a built-in way to test if two lines are identical, but there is no built-in way to tell if two lines are similar. You need to implement an algorithm that measures string similarity, such as the Levenshtein Distance - a very common Edit Distance algorithm. Lines with small edit distance can be declared similar depending on some threshold specific to your requirements.
You'll need to use an algorithm that compares the "distance" between two strings:
The closeness of a match is measured in terms of the number of
primitive operations necessary to convert the string into an exact
match. This number is called the edit distance between the string and
the pattern. The usual primitive operations are:
insertion: cot → coat
deletion: coat → cot
substitution: coat → cost
So I've got an array of integer. I want to use a loop and exclude integers that makes the equation true. So that would be like
for (int n = 0; n < first9char.Length; n++ ) {
if (first9char[n] == clickValue) {
first9char[n] = first9char[n + 1];
But then it only changes the value that is equal to not changing whole array. So is there any way to do this?
I want to use it in this loop.
if (UserSquareMethod.clickedBoxes[0] == -1) {
MessageBox.Show("You have not selected any box");
} else {
int i = 0;
do {
if (textButtonArray[clickedBox[i]].Text == "" || clickValue == "") {
textButtonArray[clickedBox[i]].Text = clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 14, FontStyle.Bold);
}
else
{
textButtonArray[clickedBox[i]].Text += "," + clickValue;
textButtonArray[clickedBox[i]].Font = new Font(textButtonArray[clickedBox[i]].Font.FontFamily, 5, FontStyle.Regular);
string[] first9char = textButtonArray[clickedBox[i]].Text.Split(new string[] { "," }, StringSplitOptions.None);
for (int j = 1; j < first9char.Length; j++)
{
for (int k = j - 1; k >= 0; k--)
{
if (first9char[j] == first9char[k])
{
if (clearNumberClicked == true)
{
first9char = Array.FindAll(first9char, x => x != clickValue);
label2.Text = first9char[0];
//int n = 0;
//for (int p = 0; p < first9char.Length; p++)
//{
// if (first9char[p] != clickValue)
// {
// first9char[n] = first9char[p];
// n++;
// label2.Text += "," + first9char[n];
// }
// }
//for (int n = 0; n < first9char.Length; n++ ) {
//if (first9char[n] == clickValue) {
// first9char[n] = first9char[n + 1];
// for ( int p = 0; p < n; p++) {
//}
//}
//}
MessageBox.Show("Clear the number" + first9char[(first9char.Length - 1)] + "and " + clickValue + " " + first9char.Length);
}
else {
first9char[j] = "";
textButtonArray[clickedBox[i]].Text = first9char[0];
MessageBox.Show("You cannot enter the same number again!"+ first9char[j]+j);
for (int m = 1; m < (first9char.Length - 1); m++) {
textButtonArray[clickedBox[i]].Text += ","+ first9char[m];
}
}
}
}
}
if (textButtonArray[clickedBox[i]].Text.Length > 9)
{
textButtonArray[clickedBox[i]].Text = first9char[0] + "," + first9char[1] + "," + first9char[2] + "," + first9char[3] + "," + first9char[4];
MessageBox.Show("You cannot enter more than 5 numbers, please clear the box if you want to enter different number." + textButtonArray[clickedBox[i]].Text.Length);
}
}
i++;
}
while (clickedBox[i] != -1);
}
}
I would use LINQ for this:
first9char = first9char.Where(x => x != clickValue).ToArray();
It just means "pick the items that don't match". If you can't use LINQ for some reason, then just keep another counter, and make sure to only loop to n from there on in:
int n = 0;
for(int i = 0; i < first9char.Length; i++) {
if(first9char[i] != clickValue) {
first9char[n] = first9char[i];
n++;
}
}
Clean and efficient.
