In this post, we will write a Java program to check whether the given number is Krishnamurthy Number or not? 1! The recursive function in NoBaseCase.java is supposed to compute harmonic numbers, but is missing a base case: public static double harmonic(int n) { return harmonic(n-1) + 1.0/n; } If you call this function, it will repeatedly call itself and never return. Let us know in the comments. 145 is Krishnamurthy Number. The output for the different test cases are:-. Syntax: returntype methodName() { //logic for application methodName();//recursive call } Example: Factorial of a number is an example of direct recursion. In this article, we'll focus on a core concept in any programming language – recursion. In this tutorial, we will learn following two methods of reversing a number. Writing code in comment?

We can analyze that the last digit will be always from 0 to 9, and every time we need to find the factorial from 0 to 9 only. check whether a given year is leap year. Armstrong number is a number that is equal to the sum of digits raised to the power as length of the number. The program will prompt user to input the number and then it will reverse the same number using while loop.
