P8805 [AtCoder] AtCoder Grand Contest 020 - Encoding Subsets
省选
题目描述

Consider the following set of rules for encoding strings consisting of 0 and 1:

  • Strings 0 and 1 can be encoded as 0 and 1, respectively.
  • If strings A and B can be encoded as P and Q, respectively, then string AB can be encoded as PQ.
  • If string A can be encoded as P and $K \geq 2$ is a positive integer, then string AA...A (A repeated K times) can be encoded as (PxK).

For example, string 001001001, among other possibilities, can be encoded as 001001001, 00(1(0x2)x2)1 and (001x3).

Let's call string A a subset of string B if:

  • A and B are equal in length and consist of 0 and 1;
  • for all indices i such that A_i = 1, it's also true that B_i = 1.

You are given string S consisting of 0 and 1. Find the total number of distinct encodings of all subsets of S, modulo 998244353.

Constraints

  • $1 \leq |S| \leq 100$
  • S consists of 0 and 1.
