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](https://codeforces.me/contest/2036/problem/C) 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);↵

fastio();↵
auto start1 = high_resolution_clock::now();↵

I would highly appreciate any help.↵
↵
Thank you for helping finally the issue is resolved, in vs code settings I added "-std=c++20" in the args section of extensions.↵
