Write a program to implement a queue using an array. In this tutorial, You are going to learn about Queue data structure and their implementation using an array in C, C++ & Java. In my previous posts, I have explained Stack and Linked List data structure.
Queue Data Structure
In Queue data structure, An element is inserted at one end called rear and deleted at other end called front. As compared to stack data structure in which insertion and deletion are allowed only at one end. Queue data structure is also called FIFO (First In First out).

Write a Java program to check prime number. Given an input integer, We have to write an efficient code to check whether a number is prime or not.
Before writing a program, let’s quickly understand what is a prime number.
A prime number is a number that is greater than 1 and it has no positive divisors other than 1 and itself.
For example – 3, 13, 7 is a prime number, as it’s divisible by 1 and itself. Similarly, 29, 19 etc. are also prime numbers.
6 is not a prime number as it’s divisible by 1, 2, 3 and 6.
