Runtime error on test case 18: Runtime error

Only main difference between the two submission is of how we implement comparison. Thoughts?

Your comparator is wrong in a case where c.ss < n.ss and c.ff = n.ff. In this case comparator will return that n = s but it isn't so. When we make a comparator we need to compare all properties of the objects we compare. For example the correct comparator for this case is looking like this bool cmp(pair<string, int> c, pair<string, int> n){ if(c.ss != n.ss) return c.ss > n.ss; return c.ff < n.ff; }

Maybe there is any point to somehow pin forever hints like that
