Problems
B'You are given a string s consisting of characters "1", "0", and "?". The first character of s is guaranteed to be "1". Let m be the number of characters in s . Count the number of ways we can choose a pair of integers a, b that satisfies the following: Compute this count modulo 998244353 . The first line contains a single string s ( 1 <= q |s| <= q 1 ,000 ). s consists only of characters "1", "0" and "?". It is guaranteed that the first character of s is a "1". Print a single integer, the count of pairs that satisfy the conditions modulo 998244353 . For the first example, the pairs in base-2 are (111, 10001), (11, 10101), (1001, 11111) . '... |
