When we search a number in the queue, we need average (1 + 2 + 3 + 4 + 5 + 6 + 7) / 7 = 4 comparisons to find the number. When we put those numbers in a binary search tree, we only need average(1 + 2 + 2 + 3 + 3 + 3 + 3) / 7 = 2.42 comparisons to find the...

Let x be a node in a binary search tree. If y is a node in the left subtree of x, then y.key≤x.key. If y is a node in the right subtree of x, then x.key≤y.key. The following figure shows an example of the binary search tree. ...

We only consider unbalanced trees here for the sake of simplicity, but in real-world scenarios efficiency of a binary search tree comes from the balanced nature, where each subtree of the root has roughly the same height. Binary trees can be traversed using three different methods named: inord...
