Logical programming is mostly asked in the interview by the interviewer to check the logical skills of the candidates. In this article, you will see the very basic and commonly asked logical programs in the interview with clear explanations such as, Fibonacci series Calculate the factorial …
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, let’s take two numbers x=20 (first variable) and y=30 (second variable), Add both number (x+y) and …

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. Let’s see the logic to check whether …

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 …
A special positive number whose sum of cubes of its individual digit is equal to that number is called an Armstrong Number. 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 …

The Perfect Number is a special type of positive number. When the number is equal to the sum of its positive divisors excluding the number, it is called a Perfect Number. For example, 28 is the perfect number because when we sum the divisors of 28, it will result in the same number. The divisors of 28 …
