Today we have a special function called Mystique Function.Mystique function for any value x is denoted by H(x). H(x) is defined as the count of positive integers such that (Let k be one of such positive integer)

1) x%k=0

2) for every integer z it satisfies (z^k-z)%k=0.

3) k>1

Now given a value x you need to print the sum of H(2)+H(3)+H(4)..H(x).
