Swapping two numbers can be also known as exchanging the numbers between two variables. The swapping of two numbers without using a third variable or a temporary variable can be done by following the below simple steps: For example, letโs take two numbers x=20 (first variable) and y=30 (second variable), Add both number (x+y) and โฆ

A Palindrome number is a special type of number. After reversing a number, if the number will be the same as the original number then that number will be called a Palindrome number. For example, some Palindrome number is as follow: 121, 242, 12321, 515, 8448, 2345432, etc. Letโs see the logic to check whether โฆ

The reverse of a given number is simply called as when the number is 123, the reverse number should be 321. In java, there are multiple ways to calculate the reverse of a given number. Here we will discuss a simple way using a while loop. Follow the below steps to calculate the reverse of โฆ
A special positive number whose sum of cubes of its individual digit is equal to that number is called an Armstrong Number.ย Example #1,The number 153 is an Armstrong number. It can be checked as follow:(1)3 + (5)3 + (3)3 => 1 + 125 + 27 => 153 Example #2,The number 371 is also an โฆ
