Transpose Matrix - Array - Easy - LeetCode - MiniTV

Transpose Matrix - Array - Easy - LeetCode - मिनी टीवी

Given a matrix A, return the transpose of A.

The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix.

Example 1:

Input: [[1,2,3],[4,5,6],[7,8,9]]
Output: [[1,4,7],[2,5,8],[3,6,9]]
Example 2:

Input: [[1,2,3],[4,5,6]]
Output: [[1,4],[2,5],[3,6]]
 

Note:

1 <= A.length <= 1000
1 <= A[0].length <= 1000

public class Solution {
    public int[][] Transpose(int[][] A) {       
        var res = new int[A[0].Length][];   
        for(int i=0;i<A[0].Length;i++){
            res[i]=new int[A.Length];    
        }
        
        for(int i=0;i<A.Length;i++){                     
            for(int j=0;j<A[i].Length;j++){
                res[j][i]=A[i][j];
            }
        }
        
        return res;
    }
}
