Recursion vs Iteration. What’s the difference between recursion and iteration. Recursion and Iteration both are two different programming approaches. In some cases recursion is best suited and in some other cases iterative way of programming is good.
In programming, repeated set of instructions can be handled either by using recursive or iterative approach in your code. So which approach you choose and why. Let’s talk about recursion vs iteration.
Implementation of Binary Search using Recursion.
Write a C program to multiply two numbers without using * multiplication operator.
Given two numbers, both numbers are positive. Write a program to multiply two numbers without using * multiplication operator. Think for a moment how to solve this problem .
You can use multiple approaches to find the solution of a problem.
C Program to Multiply Two Numbers without using *
Write a program to reverse a linked list using recursion. Given a singly linked list, we have to write a code to reverse a linked list using recursion. This question is mostly asked in interviews.
In my previous post, I have explained how to reverse a linked list using an iterative approach. In this post, We will learn how to reverse a linked list using recursion. The time complexity for both iterative and recursive approach is O(n).
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
MCQ on Recursion
Recursion is the most important concept in computer science. In my previous posts, i have written about binary search implementation using recursion and difference between recursion and iteration.
These MCQ helps you to understand the concept of Recursion.
1) Which Data Structure is used to perform Recursion?
c) Linked List
Binary Search is a searching algorithm that finds the value in a sorted array in O(logN) time complexity. In my previous post i discuss how to implement binary search using iterative method. In this post i’ll explain how to implement binary search using recursion.
What is recursion and how to use recursion in programming. If you are new to programming, then recursion concept is tough to understand. In this post, i’ll explain the concept of recursion with example.
What is Recursion ?
In Recursion, function call itself repeatedly, until the base condition is reached. It’s a much preferred way to write cleaner and shorter code for many complex problems.
Through recursion, you can reduce complex problem into smaller version.
