Can anyone suggest me a way to find the previous set bit or next set bit using Bitset STL in C++? I have seen submissions in Java where these functions are pre-defined. Any way to do the same in C++?

Thanks. Is there any function like Find_prev()?
I couldn't find anything online, so not sure but probably not
Implement it. Bitset problems are often time-critical enough that it's better to write something that works fast for a specific case.
