样例过，但是全WA

#include<iostream>
using namespace std;
int main() {
	int t;
	cin >> t;
	for (int i = 0;i < t;i++) {
		string s;
		cin >> s;
		if (s[0] == 'D' && s[1] == 'X') {
			cout << "YES" << endl;
			continue;
		}
		bool flag = false;
		for (int j = 0;j < 14 && !flag;j++) {
			if (s[j] == s[j + 1] && s[j + 1] == s[j + 2] && s[j + 2] == s[j + 3]) {
				flag = true;
			}
		}
		if (flag) {
			cout << "YES";
		}
		else {
			cout << "NO";
		}
	}
	return 0;
}
