The rule of Sudoku is this: In a 9x9 box, you need to fill in the number 1-9 into a space, and make each row and column of the square contain 1-9 of these nine numbers. Also ensure that the space in the thick line divided into 9 3x3 squares also contains 1-9 of these nine numbers. For example, if you have such a problem, you can take a closer look at each line, each column, and each 3x3 square contains 1-9 of these nine numbers.Examples:Answer:The input subject contains multiple sets of tests, s

3098: Hash killer II Time limit:5 secMemory limit:128 mbsecSpecial Judge Submit:66 Solved:22 [Submit] [Status] [Discuss] Description The weather was good this day. The hzhwcmhf God gave vfleaking a question:Here is a string s with a length of N. How many different substrings with a length of L are required.Substrings are defined as consecutive segments such as S [L], s [L + 1], and... s [R.The two strings are considered to be different whe

all substrings of length L. The vfleaking then sorts the hashes, goes to the weight, and evaluates how many different hashes to use as the result. The C + + code for its algorithm is as follows: typedef unsigned long long u64; const int MAXN = 100000; inline int hash_handle (const char *s, const int n, const int L, const int base){const int Mod = 1000000007; U64 hash_pow_l = 1;for (int i = 1; I hash_pow_l = (hash_pow_l * base)% Mod; int li_n = 0;static int LI[MAXN]; U64 val = 0;for

However, some Web developers do not have in-depth understa
