Can someone explain to me why these small changes (countdown proj) made a difference?

Question

I had the same correct results/output for all the cases for both code, but the 2nd code was the one that passed....why? Does that really matter?

//Results same but code that didn't pass:

int main() {
int n;
cin >> n;
while (n>=1){
cout<<n<<endl;
if (n % 5 == 0){
cout << "Beep \n";
}
n--;
}

return 0;
}

//Code that passed (only deleted spaces in n % 5 == 0 & changed to "Beep" << endl :

int main() {
int n;
cin >> n;
while (n>=1){
cout<<n<<endl;
if (n%5== 0){
cout << "Beep" << endl;
}
n--;
}

return 0;
}
Edit:
Ok ty Tina. Got it 👍

whitespaces in source code doesn't matter at all, however the problem is in the output, "Beep " and "Beep" are different, at least the first one is 5 bytes, the second is 4 (note the space) . that's the problem.
it's not a big deal in this case however, logically thinking and from a programming point of view your code produces wrong results and that's the first thing you should taking care of.
if you do cout << "Beep\n" ; it will pass.
