4、匹配时间复杂度为O(m*n) 5、大概需要2n次字符串比较 C代码如下 #include <stdio.h> #include <stdlib.h> #inclde <string.h> void BF(char *x, int m, char *y, int n) { int i, j; /* searching */ for (j = 0; j <= n - m; ++j) { for (i

Sometimes, brute force attacks are still done by hand, meaning that there’s an actual person sitting in some basement and playing a guessing game with your credentials. But, more often than not these days, the hackers use a brute force algorithm, or brute force password cracker, which is,...
