I am a bit confused about STL sets. STL set takes a comparator function
as input which returns true if first argument is less than second
argument, false otherwise. How does this detect equal elements ?
For eg. set<int> will not allow one int to be inserted twice. How does
it check for equality when comparator function doesn't provide that info ?
I tries to go through set code in stl_set.h but couldn;t get anything.
Thanks in advance.
Nothing will work unless u do.
