Runaround Numbers--模擬

分析：簡單模擬。。。直接按題意來就行

Code：

#include <cstdio>
#include <cstring>
#include <algorithm>
using namespace std;
 
unsigned long n;
 
int main() {
    while(~scanf("%lu", &n)) {
        while(1) {
            bool vis[50];
            char s[50];
            n++;
            sprintf(s, "%lu", n);
            int len = strlen(s);
            int flag = 0;
            for(int i = 0; i < len; i++)
                for(int j = i+1; j < len; j++){
                    if(s[i] == s[j]) {
                        flag = 1;
                        break;
                    }
                    if(flag) break;
                }
            if(flag) continue;
            memset(vis, 0, sizeof(vis));
            int cnt = 0;
            int cur = 0;
            while(1) {
                int k = s[cur]-'0';
                cur = (k+cur)%len;
                if(vis[cur]) {
                    flag = 1;
                    break;
                }
                vis[cur] = 1;
                cnt++;
                if(cnt == len) break;
            }
            if(!flag) {
                printf("%lu\n", n);
                break;
            }
            memset(s, 0, sizeof(s));
        }
         
    }
    return 0;
}
