Given a grid of integers size n x m, (use n=100 and m=4 to test it), write a C program that can create 4 (m) children where each will compute the sum
of row m (size n). Then, the waiting parent, once all children has
computed their respective sums, it will calculate the average of the sums
and display it.
For example:
Consider this grid for 3 children:
1 2 8 2
5 6 4 3
2 3 4 4
you will need 3 children, one for each row.
Sample output:
Child 1 Sum = 13
Child 2 Sum = 18
Child 3 Sum = 13
Parent Average = 14.67
