Recursion - Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function. Lets see an example of recursive code in JavaScript. function recurse() { // function code recurse(); // function code } recurse(); Here, the recurse() function is a recursive function. It is calling itself inside the function. image ( https://s3.ap-south-1.amazonaws.com/myinterviewtrainer-domestic/public_assets/assets/000/000/252/original/image.png?1616401337 ) While using recursion, one need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop. function fun() { if(condition) { fun(); } else { // stop calling fun() //code return; } } fun(); Recursive functions are very useful to solve many mathematical problems. Try the following example in the editor below. Given an input number A, find Ath fibonacci number. fib0 = 0 fib1 = 1 fibi = fibi-2 + fibi-1 (i > 1) Sample Input 3 Sample Output 2...OTP Skip By clicking on Start Test, I agree to be contacted by...Instructions from Interviewbit Start Test...
