Description

Given an N x N matrix, write a program to change the given matrix to transpose of the matrix.

NB: Try without an extra matrix.

Sample input :

3

1 2 3

4 5 6

7 8 9

Sample output:

1 4 7

2 5 8

3 6 9

 

C Program

#include <stdio.h>

 

int main()

{

            int n;

            scanf("%d",&n);

            int mat[n][n];

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<n ; j++){

                                    scanf("%d",&mat[i][j]) ;

                        }

            }

            int temp;

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<(n/2) ; j++){

                                    temp = mat[i][j];

                                    mat[i][j] = mat[j][i];

                                    mat[j][i] = temp;

                        }

            }

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<n ; j++){

                                    printf("%d ",mat[i][j]) ;

                        }

                        printf("\n");

            }

            return 0;

}

 

C++ Program

#include <bits/stdc++.h>

using namespace std;

 

int main()

{

            int n;

            cin>>n;

            int mat[n][n];

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<n ; j++){

                                    cin>>mat[i][j];

                        }

            }

            int temp;

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<(n/2) ; j++){

                                    temp = mat[i][j];

                                    mat[i][j] = mat[j][i];

                                    mat[j][i] = temp;

                        }

            }

            for(int i = 0 ; i<n ; i++){

                        for(int j = 0 ; j<n ; j++){

                                    cout<<mat[i][j]<<" ";

                        }

                        cout<<"\n";

            }

            return 0;

}

 

JAVA Program

import java.util.*;

import java.lang.*;

import java.io.*;

 

class Main

{

            public static void main (String[] args) throws java.lang.Exception

            {

                        Scanner sc=new Scanner(System.in);

                        int n = sc.nextInt();

                        int mat[][] = new int[n][n];

                        for(int i = 0 ; i<n ; i++){

                                    for(int j = 0 ; j<n ; j++){

                                                mat[i][j] = sc.nextInt();

                                    }

                        }

                        int temp;

                        for(int i = 0 ; i<n ; i++){

                                    for(int j = 0 ; j<(n/2) ; j++){

                                                temp = mat[i][j];

                                                mat[i][j] = mat[j][i];

                                                System.out.print(mat[i][j] + " ");

                                    }

                                    System.out.println();

                        }

            }

}

 

PYTHON Program

m = [[1,2,3],[4,5,6],[7,8,9]]

 

rez = [[m[j][i] for j in range(len(m))] for i in range(len(m[0]))]

for row in rez:

    print(row)
