We are required to write a JavaScript function that takes in an array of numbers of length N such that N is a positive even integer and divides the array into two sub arrays (say, left and right) containing N/2 elements each.The function should do the product of the subarrays ... Read More

Suppose, we have an array of numbers like this −const arr = [14, 54, 23, 14, 24, 33, 44, 54, 77, 87, 77, 14];We are required to write a JavaScript function that takes in one such array and counts the sum of all the elements of the array that appear ... Read More

We are required to write a JavaScript function that takes in a number and checks whether it is a Fibonacci number or not (i.e., it falls in Fibonacci series or not).Our function should return true if the number is a Fibonacci number, false otherwise.The code for this will be −const ... Read More

Suppose, we have a sorted array of literals like this −const arr = [32, 32, 63, 63, 63, 75, 75, 86, 87, 88, 89];We are required to write a JavaScript function that takes in one such array and returns the first unique number in the array.If there is no such ... Read More

We are required to write a JavaScript function that takes in an array of Numbers and returns the smallest number from it using recursion.Let’s say the following are our arrays −const arr1 = [-2, -3, -4, -5, -6, -7, -8]; const arr2 = [-2, 5, 3, 0];The code for this ... Read More

We are required to write a JavaScript function that takes in a number and returns an English count number for it.For example 3 returns 3rdThe code for this will be −const num = 3; const englishCount = num => {    if (num % 10 === 1 && num % 100 ... Read More

Suppose, we have a string that contains some capitalized English alphabets like this −const str = "Connecting to server Connection has been successful We found result";We are required to write a JavaScript function that takes in one such string and inserts a comma ', ' before the space before every ...

We are required to write a JavaScript function that takes in an array of numbers. The number should find the smallest element in the array and remove it in place.The code for this will be −const arr = [2, 1, 3, 2, 4, 5, 1]; const removeSmallest = arr => ... Read More

Given a non-negative integer, we are required to write a function that returns an array containing a list of independent digits in reverse order.For example:348597 => The correct solution should be [7, 9, 5, 8, 4, 3]The code for this will be −const num = 348597; const reverseArrify = num ... Read More

We are required to write a JavaScript function that takes in an array of numbers that contains at least one duplicate pair of numbers.Our function should return the distance between all the duplicate pairs of numbers that exist in the array.The code for this will be −const arr = [2, ... Read More
