Need clarification,

Hi everyone,

I solved a problem in the last contest and initially got a "Wrong Answer". After modifying my solution to use a map instead of a multiset, it got accepted. However, I’m not sure why my original solution with multiset failed.

Can anyone explain why using map worked while multiset didn't?

Thanks in advance for your help! https://mirror.codeforces.com/contest/1980/submission/264037860 (**WA**264037860) https://mirror.codeforces.com/contest/1980/submission/263990207 submission:263990207

In a multiset, erasing elements by value is different from erasing it by iterator.
