*  Problem Name   : makerowcolzero
*  Used In        : Practice
*  Used As        : Matrix
*  Problem        :
*                   You are given the MxN matrix with numbers.Once you see the '0' you have to make whole row and column
*                   referring cell to the zero.
*  Example        : 
*                   Input  :-
*                           { {1,2,3,4,0,9},
*                             {8,9,10,11,12,3}}
*                   Output :-
*                           {{0,0,0,0,0,0},
*                            {8,9,10,11,0,13}}
*  Thoughts       => 
*                    Brute Force / Naive Approach :- We identify the row X column position and with respect to that
*                                                    which triggers two separate loops to make the values zero.
