if element is 0 in matrix then entire row and column should be set to 0
i got this from sumwhr
void makeRowColZero(int (*a)[COL])
{
int i, j, k;
k = 0;
for(i = 0; i < ROW; i++)
for(j = k; j < COL; j++)
{
if(0 == a[i][j])
{
for(k = 0; k < ROW; k++)
a[k][j] = 0;
for(k = 0; k < COL; k++)
a[i][k] = 0;
i++;
j++;
k = j;
continue;
}
}
}
in the end continue???it takes to loop start but if it is not used
even then we can go to start after the loop fiteration is over....
