I want to add something. There are 6 possibilities for Depth First Search Algorithm according to the starting point in data structure. D refers to the Data, L refers to the Left, R refers to the Right pointer. The possibilities are; A-PreOrder (1-DLR, 2-DRL), B-InOrder (3-LDR, 4-RDL), C-PostOrder (5-LRD, 6-RLD)

Explaining recursive functions is challenging and often confusing to the neophyte. Nevertheless, you tackled the challenge faultlessly. One wonders if, when searching, the algorithms would be more efficient if one compared the 'target' with the data and choosing the appropriate algorithm on the result. Are there generic algorithms for balancing the tree, should one side of a node gets much 'heavier' than the other?
