Problem Statement
Given is an integer N.
Determine whether there is a pair of positive integers (A, B) such that 3^A + 5^B = N, and find one such pair if it exists.
Input
Input is given from Standard Input in the following format:
N
Output
If there is no pair (A, B) that satisfies the condition, print -1.
If there is such a pair, print A and B of one such pair with space in between. If there are multiple such pairs, any of them will be accepted.
Constraints
- $1 \leq N \leq 10^{18}$
- All values in input are integers.
Sample Input 1
106
Sample Output 1
4 2
We have 3^4 + 5^2 = 81 + 25 = 106, so (A, B) = (4, 2) satisfies the condition.
Sample Input 2
1024
Sample Output 2
-1
Sample Input 3
