I am doing a problem which requires similar operation in which we have to find element smaller than x then delete it from multiset then find for another x. ↵
I am using an approach that is giving TLE for 10^5 constraints↵

↵
[My Code](https://pastebin.com/skz4FF8j)↵
↵
Is my method to find that element wrong or is it anything else.↵
PS -> I am not very clear on how to find Elements Lesser than X in set/multiset and its working I used ↵
auto it = *lower_bound(st.rbegin(),st.rend(),a[i],greater<int>());↵
As I saw it in blog can anyone also explain how it works
