문제

Consider sets of natural numbers. Some sets can be sorted in the same order numerically and lexicographically. {2, 27, 3125, 9000} is one example of such sets; {2, 27, 243} is not since lexicographic sorting would yield {2, 243, 27}.

Your task is to write a program that, for the set of integers in a given range [A, B] (i.e. between A and B inclusive), counts the number of non-empty subsets satisfying the above property. Since the resulting number is expected to be very huge, your program should output the number in modulo P given as the input.

입력

The input consists of multiple datasets. Each dataset consists of a line with three integers A, B, and P separated by a space. These numbers satisfy the following conditions: 1 ≤ A ≤ 1,000,000,000, 0 ≤ B − A < 100,000, 1 ≤ P ≤ 1,000,000,000.

The end of input is indicated by a line with three zeros.

출력

For each dataset, output the number of the subsets in modulo P.
