Matrix Transpose In-Place

Difficulty : Easy

Categories :

  • Arrays

Given an n x n matrix, transpose the matrix in-place. The transpose of a matrix is obtained by flipping the matrix over its main diagonal, switching the matrix's row and column indices. Do not return a new matrix; modify the input matrix in-place.

Constraints:

  • 1 ≤ n ≤ 100
  • -1000 ≤ matrix[i][j] ≤ 1000
  • Modify matrix in-place

Examples:

Input:
[[1,2,3],
 [4,5,6],
 [7,8,9]]
Output:
[[1,4,7],
 [2,5,8],
 [3,6,9]]
Explanation: Original matrix rows become columns
Input:
[[1,2],
 [3,4]]
Output:
[[1,3],
 [2,4]]
Explanation: 2x2 matrix transposed
