Problem 792. Set some matrix elements to zero

Created by Aurelien Queffurust

First get the maximum of each row, and afterwards set all the other elements to zero. For example, this matrix:

1 	2 	3 	4
5 	5 	6 	5
7 	9 	8 	3

should become:

0 	0 	0 	4
0 	0 	6 	0
0 	9 	0 	0

Input will never be empty.

If a row has the same maximum in different columns , display the first occurrence:

In the below example, the second row has twice the number 8 as maximum , the output will display the first 8 (column2) :

   x =
       5     4     5
       2     8     8
   should become :
     5     0     0
     0     8     0
