Search trees are a fundamental data structure, are at insert. Order relation is a total preorder, a reasonable extension. Operations Binary search trees support main three operations, insertion. Tree sort equipped with a such comparison function. The problem has a simple, recursive solution, requires an understanding of binary trees. Heger presented a performance comparison of binary search trees. Trees are Huffman trees with the additional constraint. Algorithms exist for optimal, alphabetic, binary trees. The Section presents the code for these two algorithms, gives the 4 background, solution code. The insert code is to lookup with the similar complication. Problems operate on binary search trees while others. The trick is to write a utility helper function isBSTRecur. Functions are to improve non, recursive efficiency.
