题目描述

参考了大佬的思路，简化了一下

C++ 代码

#include <iostream>
#include <string>
using namespace std;

int main() {
    string a, b;
    cin >> a >> b;

    if (a.size() < b.size()) {
        swap(a, b);
    }

    int f = 0;
    for (int i = 0; i < a.size(); ++i) {
        if (a[i] == b[0]) {
            int k = 0;
            for (; k < b.size(); ++k) {
                if (a[(i + k) % a.size()]!= b[k]) {
                    break;
                }
            }
            if (k == b.size()) {
                f = 1;
                break;
            }
        }
    }
    if (f) 
        cout << "true" << endl;
    else 
        cout << "false" << endl;
    return 0;
}
