#include
using namespace std;
void test_case(){
int n;
int coin5=0,coin10=0,coin15=0;
cin>>n;
while(n–){
int c;
cin>>c;
if(c==5){
coin5++;
}else if(c==10){
if(coin5==0){
cout<<“NO”<<endl;
return;
}else{
coin5–;
coin10++;
};
}
else if(c==15){
if(coin10==0){
if(coin5<2){
cout<<“NO”<<endl;
return;
}else{
coin5-=2;
coin15++;
};
}else{
coin10–;
coin15++;
};
};
};
cout<<“YES”<<endl;
}
int main()
{
int t;
cin>>t;
while(t–)
test_case();
return 0;
}

Bro format your code or give link to your submission. Use ``` at the start and the end of code for formatting.

19 line remove semicolon

9

and also return after giving every output

10

First you don’t have to put semicolon after else. Second, your code is not even working for sample TC. This is because, you are returning before taking all the input. You may see this CodeChef: Practical coding for everyone

11

but whats the use of taking further input if it fails at a certain input

12

If that input is not given then it will become input for next TC

oh right! thanks alot!
