Why do I get time limit exceeded? PROBLEM: Odd Sum

#include
#include
#define ll long long

void FastIO(){
std::ios_base::sync_with_stdio(0);
std::cin.tie(0);
std::cout.tie(0);
}

void solve(){
ll n;
std::cin>>n;
ll result=1+(n-2)*(n-1);
std::cout<<result<<std::endl;
}

int main(){
FastIO();
int t;
std::cin>>t;
while(t–){
solve();
}
return 0;
}

std::cout<<std::endl

is a slow operation as it calls std::cout.flush() implicitly after sending ‘\n’ to the default output stream. This is useful only in interactive problems.

Replace std::endl with ‘\n’, and check if this fixes the TLE issue.

You’re right, thank you. So is better to use ‘\n’ in general right?

That’s right, except in interactive problems as I said.
