Solve InterviewCake's bst-checker problem
Write a function that returns true if a given binary tree is a valid binary search tree (i.e. if all of root's left nodes are less than root.value, all of root's right nodes are greater than root.value, and both left and right subtrees are also valid binary search trees).
