最后还是靠统计字符的出现次序过的。。。为什么原生态统计ASCII码值对应hash不行呢?哪位路过的大牛给解释一下吧~#include <stdio.h> #include <string.h> #define MAX 40000000 bool hash[MAX]={0}; char str[MAX]; int main() { int n,nc,len,count=0,flag=0; scanf ("%d %d",&n,&nc); scanf ("%s",str); len=strlen(str); for (int i=0;i<len;i++) { int sum=0; flag=0; for (int j=i;j<i+n&&j+n<len;j++) { flag=1; // printf ("%c",str[j]); sum=sum*nc+str[j]; } //printf ("\n"); if(!hash[sum]&&flag) { hash[sum]=1; count++; } } printf ("%d\n",count); //while(1); } Followed by:
