Ch 1 introduction
Algorithm is a step by step procedure for solving a problem. It is like a recipe in cooking.
Algo have the following properties:
Input:

These contain several examples of ADTs (abstract data types) and you are expected to be

AVL trees
As we have seen, depending on the order in which you insert data into a
BST, the shape of the tree will be different.
Consider inserting the same data items in the following two orders:
Eg1: 10 20 40 30 50 60 70
Eg2: 40 20 10 30 60 50 70
