Write a function that, given a square matrix m, tells if it is symmetric or not.

Remember that a matrix m is symmetric if mi,j=mj,i for any i and for any j.

Precondition

m is a square matrix n× n with n ≥ 0.

Interface

C++
typedef vector< vector<int> > Matrix;
 
bool is_symmetric(const Matrix& m);
Java
public static boolean isSymmetric(int[][] m);
