Write a program to print factorial of a number in PHP. In this tutorial, We are going to write a PHP code to print factorial of a number using iterative as well as recursive approach. Before solving this problem let’s understand what is factorial.
Program to Print Factorial of a Number in PHP
Write a program to check whether a number is palindrome or not using php code. How to solve this problem.
Write a java program to print Fibonacci series up to N number, where N is the input integer.
Write a program to print 1 to 100 numbers without using loop. Using loop, (for and while loop) we can easily solve this problem. Think for a moment how do you solve this problem without using a loop. We can solve this problem using recursion.
Write a C program to print Fibonacci Series using recursion. Given an input number, we have to write a code to print Fibonacci series up to that number using Recursion.
This question is very important in terms of technical interviews.
You can check my previous post for PHP script to print Fibonacci series in PHP.
What is Recursion?
In recursion, A function calls itself until the base condition is reached. Recursive code is much cleaner and shorter as compared to iterative code.
For better understanding you can my previous post on recursion and what’s the difference between recursion and iteration.
For practice, you can solve Objective Question on Recursion
Write a program to implement a stack using linked list. In my last post, I have explained the implementation of a stack data structure using an array. In this post, I’ll explain how to implement a stack data structure using linked list.
