( 998 ) E Vasya and Big Integers PROGRAMMING binary search data structures dp hashing strings 2500

B'Vasya owns three big integers -- a, l, r . Let 's define a partition of x such a sequence of strings s_1, s_2, ... , s_k that s_1 + s_2 + ... + s_k = x , where + is a concatanation of strings. s_i is the i -th element of the partition. For example, number 12345 has the following partitions: ["1", "2", "3", "4", "5"], ["123", "4", "5"], ["1", "2345"], ["12345"] and lots of others. Let 's call some partition of a beautiful if each of its elements contains no leading zeros. Vasya want to know the number of beautiful partitions of number a , which has each of s_i satisfy the condition l <= s_i <= r . Note that the comparison is the integer comparison, not the string one. Help Vasya to count the amount of partitions of number a such that they match all the given requirements. The result can be rather big, so print it modulo 998244353 . The first line contains a single integer a~(1 <= a <= 10^{1000000}) . The second line contains a single integer l~(0 <= l <= 10^{1000000}) . The third line contains a single integer r~(0 <= r <= 10^{1000000}) . It is guaranteed that l <= r . It is also guaranteed that numbers a, l, r contain no leading zeros. Print a single integer -- the amount of partitions of number a such that they match all the given requirements modulo 998244353 . In the first test case, there are two good partitions 13+5 and 1+3+5 . In the second test case, there is one good partition 1+0+0+0+0 . '...
