题目大意:找出字串最大循环次数
方法:和上一个一样
#include#include #include #include using namespace std;int next[1000010];char str[1000010];void getnext(char *s, int len){ int i = 0; int j = -1; next[0] = -1; while(i < len) { if(j == -1 || str[i] == str[j]) next[++i] = ++j; else j = next[j]; }}int main(){ int n; int cas = 0; while(~scanf("%s",str) && str[0]!='.') { int len = strlen(str); getnext(str,len); if(next[len] && len%(len-next[len])==0) printf("%d\n",len/(len-next[len])); else printf("1\n"); } return 0;}
