Min-Max Matrix

Given a square matrix $M$ of $n\times n$ (with $n\geq 1$ ) of integers, its matrix minMax is the matrix $mM$ of $n\times 2$ such that for all $i$ (with $0\leq i<n$ ), $mM[i][0]$ is the minimum element of the $i$ -th row of $M$ and $mM[i][1]$ is the maximum element of the $i$ -th column of $M$ .

For instance, if $M = [[1,2,3], [3,1,2], [2,3,1]]$ , $mM = [[1,3], [1,3], [1,3]]$

Implement the @min_Max(M)@ function that given the square matrix $M$ returns its minMax matrix.

You can use the @min()@ and @max()@ functions of Python, that given a list, they return their minimum and maximum element respectively.
