chen_h is poor at math. Today, chen_h falls across a puzzle problem, so he has no choice but to appeal to you. This problem describes that:

f(x) = 5x^13 + 13x^5 + kax

input a nonegative integer k(k<10000), to find the minimal nonegative integer a, make the arbitrary integer x, 65|f(x) if no exists that a, then print "no".

Input

The input contains several test cases. Each test case consists of a nonegative integer k.

Output

The output contains a string "no", if you can't find a, or you should output a line contains the a.
