Min-Max Matrix

Given a square matrix $M$ of integers, with size $n\times{n}, n\ge{1}$ , its matrix minMax is a matrix $mM$ with size $x\times{2}$ such that for all $i, 0\le{i}\le{n}$ , element 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 is the matrix

1 2 3
6 7 4
8 9 5

then mM will be:

1 8
4 9
5 5

Implement a function minMax(M) that given a square matrix M returns its minMax matrix.

You can use the python min and max functions to compute the maximum and minimum of a list.

Observation

Only the function is expected. Remember to comment out any testing main program you may have.
