I have understood the solution,I just need to know where my solution is going wrong as it is passing almost all test cases.
I’ll have a look soon…
I’m out at the moment.
multiset.erase(key) removes all elements equal to
key. To remove a single instance, you can instead do
multiset.erase(multiset.find(key)). Generally you should first check whether
multiset.find(key) is past-the-end iterator, but
key in guaranteed to exist in the multiset in this situation so it is not necessary. I made the change in your code, and it works- here
I used multiset for the first time so didn’t knew about it. I was stuck on this for hours. Thanks a lot man.
I didn’t know about this too, but managed to find the bug by comparing with some accepted solutions.
