MB1 - PP numbers |
PP numbers are prime numbers and palindromes in decimal notation at once. Your task is to find n-th PP number in ascending order. Then calculate product of its non-zero digits - let's call it m - and find m-th prime number in ascending order.
Input
In the first line of input there is one positive integer Z (1 ≤ Z ≤ 1000) which states the number of test cases. Following Z lines contain test cases.
Each test case consists of one positive integer n (1 ≤ n ≤ 113) which states the number of PP number to find.
Output
For each test case print in separate line two numbers: n-th PP number and m-th prime number.
Example
Input:
3 1 5 2
Output:
2 3 11 2 3 5

there is still some problem with the input files, sir. my precomputation solution gave WAs, while predefined array solution gave AC.. why? |
