Code working fine on leetcode but here giving wrong output

#1

bool isHappy(int n) {
set st;
while (1)
{
n = digitSum(n);
if (n == 1)
return true;
if (st.find(n) != st.end())
return false;
st.insert(n);
}
}
int digitSum(int n){
int res = 0;
while(n != 0){
int digit = n % 10;
res += digit*digit;
n /= 10;
}
return res;
}

Issue was only with output format, try to submit it if it doesn’t gets pass. Do let me know.
