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.
Thank you for helping finally the issue is resolved, in vs code settings I added "-std=c++20" in the args section of extensions.
// this is the corrected code ~~~~~~~~~~~~~~~~~~
include <bits/stdc++.h>
using namespace std; using namespace chrono;
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 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"; }}
int main() { #ifdef DEBUG freopen("Error.txt", "w", stderr); #endif
// Fast input/output ios::sync_with_stdio(false); cin.tie(0); // Time measurement (for debugging purposes) auto start1 = high_resolution_clock::now(); int tt; cin >> tt; // Number of test cases while (tt--) { solve(); // Solve each test case } // Measure time and print auto stop1 = high_resolution_clock::now(); auto duration = duration_cast<microseconds>(stop1 - start1); #ifdef DEBUG cerr << "Time: " << duration.count() / 1000 << " ms" << endl; #endif return 0;} ~~~~~~~~~~~~~~~~~~~
Bro I don't want the corrected code, I want to know how to parse my cph judge so that it can run with auto key word and I can use range based for loop
use using namespace chrono; after using namespace std;
and instead of fastio() use
ios::sync_with_stdio(false); cin.tie(0);
How will that make range-based for-loops work?
Sorry I did not notice that
What version of C++ are you on? It looks like the compiler doesn't support C++11.
I'm not very familiar with Competitive Programming Helper. Did it install the compiler or did you install one separately? What compiler and what version is it? (It's just a VS code extension to parse inputs, right? I don't think it is the issue. Does the code work if you compile it otherwise?)
Before I installed the Competitive Programming Helper extension I always wrote and compiled my code in C++20.
-I installed the cph judge from vs code extensions it parses input and output using codeforces api from a ongoing problem and displays it in my vscode .cpp file, it can run testcases locally in my mac.
-As for the compiler I use Apple clang version 16.0.0 which I installed using "brew install gcc"
-yes the code works perfectly if I compile it otherwise as shown below ~~~~~ * Executing task: clang++ -std=c++20 -g /Users/badribishaldas/Desktop/Home/Coding/CPP/2036C.cpp -o /Users/badribishaldas/Desktop/Home/Coding/CPP/2036C * Terminal will be reused by tasks, press any key to close it. ~~~~~
-The issue is When I run my file using the cph judge extension it throws the error which I wrote in the above blog
Thank you for taking your time to address this issue.
