Data structure and algorithm

Data structure is a method of organising large amount of data more efficiently so that any operation on that data become easy to understand.

There are two types of data structure.
1. linear data structure
2. non linear data structure

1.linear data structure ;- it is a method of organising data in a sequencial structure. for ex array linkedlist stack queue.

2.non linear data structure;- it is a method of organising data element in random way that is called non linear data structure. for example tree ,graph,heaps etc.
