Now that you know what a binary search tree is, we will look at how a binary search tree is constructed. The search tree in Figure 1 represents the nodes that exist after we have inserted the following keys in the order shown: \(70,31,93,94,14,23,73\).Since 70 was the first key inserted into the tree, it is the root.

Binary Search Tree != Binary Tree. A Binary Search Tree has a very specific property: for any node X, X's key is larger than the key of any descendent of its left child, and smaller than the key of any descendant of its right child. A Binary Tree imposes no such restriction. A Binary Tree is simply a data structure with a 'key' element, and two ...

5.4. The Binary Search¶. It is possible to take greater advantage of the ordered list if we are clever with our comparisons. In the sequential search, when we compare against the first item, there are at most \(n-1\) more items to look through if the first item is not what we are looking for. Instead of searching the list in sequence, a binary search will start by examining the middle item.

Binary search is a fast algorithm for searching sorted sequences. It runs in about log2 N time, as opposed to an average run time of N/2 for linear search. For large lists that you need to search multiple times, it might well be more efficient to sort and use binary search instead of sticking to a linear search.
