Matrix Symmetry Check Problem Statement

You are provided with a square matrix. Your task is to determine if the matrix is symmetric. Return true if it is symmetric, otherwise return false.

A matrix is considered symmetric if its transpose is identical to the original matrix.

Example:

Input:

T = 1
N = 3
Matrix = [[1, 2, 3], [2, 4, 5], [3, 5, 6]]

Output:

true

Explanation:

The given matrix is symmetric because its transpose is equal to the matrix itself.

Constraints:

1 ≤ T ≤ 10

1 ≤ N ≤ 10²

-10⁹ ≤ data ≤ 10⁹

Time Limit: 1 sec

Accepted Answer

Determine if a square matrix is symmetric by checking if its transpose is equal to itself.

Iterate through the matrix and compare each element with its corresponding element in the transpose
If any pair of elements are not equal, return false immediately
If all pairs are equal, return true at the end
