Factset Question: Subarray of k Size from a Array that has given Mean

/*
C program: print a sub-array b of size k that have mean m from a 
given array a of size n.

Description: Question asked in written (codding) test of FactSet
recruitment drive at NIT Durgapur Campus on September 14, 2016.

Example 1: int a[] = {1,2,3,4,5,6,7,8,9,0}, k = 4, m = 6
then b will be b[] = {7,8,9,0} and should print 7 8 9 0
