Hi all,

I hope you are having a great day.

I was solving this problem, which is quite simple with the policy based Data Structure Ordered Set.

However, I wanted to create a Ordered Multiset, but I couldn't get it to work, as I could not erase from the resulting data structure.

Can someone please help me by giving me the code for the ordered_multiset which supports insertion,deletion, order_by_key, and size?

Thanks,

-BC
