To find the mean of the elements of the array.
Mean = (Sum of elements of the Array) / (Total no of elements in Array)
Input : 1 2 3 4 5 Output : 3 Input : 1 2 3 Output : 2
To find the mean using recursion assume that the problem is already solved for N-1 ie you have to find for n
Sum of first N-1 elements = (Mean of N-1 elements)*(N-1) Mean of N elements = (Sum of first N-1 elements + N-th elements) / (N)
Note : Since array indexing starts from 0, we access N-th element using A[N-1].
