We have to write a function maximumDifference() that takes in a positive number n and returns the difference between the maximum number and the minimum number that can be formed out of the number n.For example −If the number n is 203, The maximum number that can be formed from ... Read More

We are required to write a function that takes in a string of definite characters and the function should return the difference between the count of vowels plus other characters and consonants in the string.For example −If the string is −"HEllo World!!"Then, we have 7 consonants, 3 vowels and 3 ...

We are required to write a function, say nearestPalindrome() that takes in a number n and returns a palindromic number that is nearest to the number n.For example −If the input number is 264, then the output should be 262If the input number is 7834, then the output should be ... Read More

Let’s say, we have an array of arrays that contains some elements like this −const arr = [3, 5, 7, 2, [4, NaN, null, 4, 8, [3, undefined, 24, null], null, 5, 1], NaN, 45, 2, 1];Our job is to write a recursive function that takes in this nested array ... Read More

We are required to write a function, say reverseSum() that takes in two arrays of Numbers, let’s say first and second and returns a new array that contains, Sum of first element of first array and last element of second array as first element, sum of second element of first ... Read More

We are required to write a function that takes a positive integer n and returns an array of next n leap years. We will break this problem into three parts −Part 1: Finding current year via JSThe code to find current year via JS will be −// getting the current ... Read More

We are required to write a function with a while-statement that determines the length of the largest consecutive subarray in an array of positive integers.For instance −If the input array is −const input = [6, 7, 8, 6, 12, 1, 2, 3, 4] --> [1, 2, 3, 4]Then the output ... Read More

Given an array of arrays, each of which contains a set of numbers. We have to write a function that returns an array where each item is the sum of all the items in the corresponding subarray.For example −If the input array is −const numbers = [    [1, 2, ... Read More

Let’s say, we are required to write a recursive function that sums all the elements of an array of Numbers but with a twist and the twist is that the recursive function we write cannot initialize any extra variable (memory).Like we cannot use a variable to store the sum or ... Read More

We are required to write a JavaScript function that takes in a number and returns a boolean based on the fact whether or not it comes in the fibonacci series.For example −If the function call is like this −fibonacci(12); fibonacci(89); fibonacci(55); fibonacci(534);Then the output should be −False true true falseNow, ...
