We are given two arrays say, arr1 and arr2 of positive Numbers. The number of values in both the arrays are the same.We are required to write a function that finds the maximum sum of products of their elements.Each element in arr1 has to be multiplied with exactly one element ... Read More

We are required to write a JavaScript function that takes in three unsorted numbers and returns the middlemost of them using minimum number of comparisons.For example: If the numbers are −34, 45, 12Then our function should return the following −34ExampleFollowing is the code −const num1 = 34; const num2 = ...

We are required to write a JavaScript function that takes in an array of numbers and returns a subarray of two elements from the original array whose sum is closest to 0.If the length of the array is less than 2, we should return the whole array.For example: If the ... Read More

We are required to write a JavaScript function that takes in an array of numbers of length N (N should be even) and divides the array into two sub-array (left and right) containing N/2 elements each and do the sum of the subarrays and then multiply both the subarrays.For example: ... Read More

We are required to write a JavaScript function that takes in one such array and counts the sum of all distinct elements of the array.For example: Suppose, we have an array of numbers like this −const arr = [1, 5, 2, 1, 2, 3, 4, 5, 7, 8, 7, 1];The ... Read More

We are required to write a JavaScript function that takes in a number and checks whether it falls in Fibonacci series or not. We should return a boolean.Following is the code to check for Fibonacci −Exampleconst num = 89; const isFib = query => {    if(query === 0 || ... Read More

Suppose, we have a sorted array of literals like this −const arr = [2, 2, 3, 3, 3, 5, 5, 6, 7, 8, 9];We are required to write a JavaScript function that takes in one such array and returns the first number that appears only once in the array. If ... Read More

We are required to write a JavaScript function that takes in a Number, say n, and we are required to check whether there exist such three consecutive natural numbers (not decimal/floating point) whose sum equals to n.If there exist such numbers, our function should return them, otherwise it should return ... Read More

We are required to write a JavaScript function that takes in a lowercase string and sorts it in the reverse order i.e., b should come before a, c before b and so on.For example: If the input string is −const str = "hello";Then the output should be −const output = ... Read More

We are required to write a JavaScript function that takes in a number, constructs a new number from the first and last digit of that number and returns the difference between the original number and the number thus formed.For example: If the input is 34567Then the corner digits number will ...
