Continuous Variant of the Chinese Remainder Theorem. x is the data being searched for within the tree, len is just the amount of nodes it has to travel to come up with the matching node if it exists. The reason why root gets NULL again and again is that it actually never changes its value to something else than NULL. Your insertElement does not always return a value. Am I betraying my professors if I leave a research group because of change of interest? This is not a binary tree programming problem in the ordinary sense -- it's more of a math/combinatorics recursion problem that happens to use binary trees.
