This chapter starts with a quick search strategy called binary search. This strategy assumes that the set of objects in which we will search is already sorted. The authors explain sequential search, binary search, and recursion – a recursive function is a function that is defined by itself or...

Algorithm for testing whether a binary tree is a binary search tree Algorithm 1 In this approach, we treat each node as the root of its subtree and check if the left subtree contains any element greater than the root value and if the right subtree contains any element less than the root ...
