Why aren't Java Collections remove methods generic?
...are too many reasonable programs that could not be generified if
you only allow the generic type of the collection as parameter type.
The example given by him is an intersection of a List of Numbers and a
List of Longs.

Are duplicate keys allowed in the definition of binary search trees?
...cluded. For example, the example algorithms in the MIT Algorithms book usually present examples without duplicates. It is fairly trivial to implement duplicates (either as a list at the node, or in one particular direction.)
Most (that I've seen) specify left children as <= and right children ...

Regex lookahead, lookbehind and atomic groups
