Question

Implement the following C code in MAL and develop a small main program that tests your implementation on an integer array. You must use nested procedures in your implementation. int getArrAvg (int Arr) int sum0 for (int i = 0; i < 10; i += 1) sum-addfn (sum, Arr[i]) return sum/10; int addfn (int a, int b) return ab;

In mips code please
