Implementation of Queue using Stack

Queue is a data structure used for storing collection of data where order in which data is arriving is important. In Queue, insertion and deletion both happened from the different end.
Data insertion are done at one end which is known as “rear end” while data deletion are done at other end known as “front end“. The data which is arrived first will be deleted first in Queue. This data ordering is called as First in First out or FIFO.
Before going ahead have a look into Queue basics, Stack basics and Stack Implementation.

Program to implement two Stacks in an array

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 Generic Stack Implementation.

Program to check if a Linked List is Palindrome

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.

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.
