Program to reverse a Stack

Stack is a data structure used for storing collection of data where order in which data is arriving is important. In Stack, insertion and deletion both happened from the same end which is known as “Top”.
The data which is arrived last will be deleted first in Stack. This data ordering is called as Last in First out or LIFO. Before going ahead have a look into Stack basics and Stack Implementation.

Program to find Intersection of Two Linked Lists

Linked List is a data structure used for storing collection of data where successive elements are connected through pointers and the size of linked list can grow or shrink dynamically.
In short, Linked list can be thought as similar to array in which traversal can happen through pointers instead of indexes. Before going ahead have a look into Linked List Basics and Linked List Implementation.
