Write a program to calculate factorial of a given number in Java, using both recursion and iteration. Since factorial is a naturally recursive operation, it make sense to use recursion to solve this problem but its not always the best way.
Declare recursive function to check palindrome Before we check palindrome numbers using functions, let us first define our function. First give a meaningful name to our function, say isPalindrome. Along with this declare and define another function to find reverse of numbersay int reverse int num.
Next, the isPalindrome function takes an integer to find reverse as input. Therefore, pass an integer value to the function i.
Finally function must return boolean true or false value based on palindrome condition. In C we represent boolean values with 1 or 0. Hence the function must return an integer. Considering the above points function declaration to check palindrome number is - int isPalindrome int num.
Logic to check palindrome number using recursion We know that to check a palindrome number we first need to reverse the number then check whether the given number is equal to its reverse or not.
If the given number is equal to its reverse then the number is palindrome otherwise not. In my previous post I explained how to find reverse of a number recursively.
Here we will use the same recursive approach to find reverse and then will compare the reversed number with original number.R Program to Find the Factorial of a Number Using Recursion In this example, you’ll learn to find the factorial of a number using a recursive function.
To understand this example, you should have the knowledge of following R programming topics. There are a number of solutions when we have to code factorials and we can experiment with any number-crunching software.
1. Function ‘factorial’ 4. Recursion. We could even use a recursive method to calculate a factorial.
without using the Matlab factorial function. As a condition.
C Program to Find the Factorial of a Number using Recursion Posted on February 14, by Manish This C Program prints the factorial of a given number using recursion. Nov 15, · Java program – Factorial using recursion November 15, Decimal to hexadecimal program in java November 15, Fibonacci series using recursion in java November 15, This is a Java Program to Find Factorial Value Without Using Recursion.
Enter any integer of whch you want to find factorial as an input. Now we use for loop to calculate the factorial of given number. java program to find factorial of a given number using recursion By Chaitanya Singh | Filed Under: Java Examples Here we will write programs to find out the factorial of a number using recursion.
