Describe your issue
When I run the problem on the CodeChef IDE, I get a “Judge Error” after submission. I am using the interactive problem approach where the system provides responses to my guesses. The code works fine in local tests, and the input/output handling is implemented with proper flushing of the output.

using namespace std;
vector sq; // Stores perfect squares
void sieve() {

}
void Go() {
for (int i = 0; i < sq.size(); i++) {
cout << sq[i] << endl; // Make a guess
cout.flush(); // Flush output immediately
int res = 0;
cin >> res; // Get response
if (res == 1) {
return; // Correct guess, exit
} else if (res == -1) {
exit(0); // Invalid input, exit
}
}
cout.flush(); // Ensure final output is flushed
}
int32_t main() {
ios_base::sync_with_stdio(false);
cin.tie(0); // Optimize input/output
sieve(); // Generate all perfect squares from 1 to 1,000,000
int t = 1;
cin >> t; // Read number of test cases
while (t--) {
Go(); // Start the guessing process
}
return 0;
