Hello Codeforces,

I am beginner here I am having problems regarding the competitive programming helper extension and would appreciate some help regarding it.

When I run a testcase for example Anya and 1100 problem and for this problem my code is

bool check(string& s, int i)
{
    if (s[i] == '1' && s[i + 1] == '1' && s[i + 2] == '0' && s[i + 3] == '0')
        return true;
    return false;
}

void solve()
{
    string s; cin >> s;
    int q; cin >> q;
    int n = s.size();
    set<int> exists;
    for (int i = 0; i < n - 3; i++)
        if (check(s, i))
            exists.insert(i);
    while (q--)
    {
        int i; cin >> i; i--;
        char c; cin >> c;
        s[i] = c;
        for (int j = i - 3; j <= i; j++)
        {
            if (j < 0 || j + 3 >= n)
                continue;
            if (exists.find(j) != exists.end())
                exists.erase(j);
            if (check(s, j))
                exists.insert(j);
        }
        if (exists.size())
            cout << "YES\n";
        else
            cout << "NO\n";
    }
    vector<map<int, int>> ls = { {{1, 2}}, {{3, 4}}, {{4, 5}} };

    for (const auto& m : ls) {  // Iterate over each map in the vector
        for (const auto& pair : m) {  // Iterate over each key-value pair in the map
            cout << pair.first << " " << pair.second << endl;
        }
    }
}

int main() {
    #ifdef DEBUG
        freopen("Error.txt", "w", stderr);
    #endif
        fastio();
        auto start1 = high_resolution_clock::now();
        int tt;
        cin>>tt;
        while(tt--) {solve();}
        auto stop1 = high_resolution_clock::now();
        auto duration = duration_cast<microseconds>(stop1 - start1);
    #ifdef DEBUG
        cerr << "Time: " << duration . count() / 1000 << endl;
    #endif
}

I am getting the following errors in my output

I would highly appreciate any help.
