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://codeforces.net/contest/1980/submission/264037860 (**WA**264037860) https://codeforces.net/contest/1980/submission/263990207 submission:263990207

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