PRIMPERM - Prime Permutations |
Given two positive integers n and m, we call m a prime permutation of n, if m is prime and can be obtained by zero or more permutations of the digits of n. Permutations with leading zeros are invalid.
Input
Input starts with a positive integer t<104 in a single line, then t lines follow.
Each of the t lines contains one positive integer n<107.
Output
For every n print the number of distinct prime permutations of n in a single line.
Example
Input: 2 13 110 Output: 2 1
Hint:If your solution times out, you may try the tutorial version with a longer time limit.

Hmm, I narrowly got AC in the time limit in 2011 but it turned to TLE after cluster change, guess I'll have to revisit. Edit: There were some funny things going on in that old code. Last edit: 2015-01-18 23:39:41 |
