这题呢就是一个模拟，没了……

#include <bits/stdc++.h>
using namespace std;

int main(){
    int n;
    scanf("%d", &n);
    while (n--) {
        string s; cin >> s;
        for (int i = 0; i < s.size(); i++) {
            if (s[i] == '0') cout << s[i];
            else {
                int j = i + 1, cnt = 1;
                while (s[i] == s[j] && j < s.size()) {
                    j++; cnt++;
                    if (cnt == 5) { printf("11111"); i = j; break; }
                }
                if (cnt != 5) cout << s[i];
            }
        }
        cout << endl;
    }
    return 0;
}
