Tree data structure in c programs

Anyways thanks!!! The Stig: Ah, but this is purely a starting point -- it doesn't currently support looking up particular values should be pretty easy , deletion somewhat non-trivial , maintaining balance decidedly non-trivial , etc. Akshay Ithal Akshay Ithal 1 1 1 bronze badge.
