The easiest way to find the two largest elements is by first sorting the elements and then returning the elements stored in the 0th and first index. A simple way to find the largest and second-largest number is that sort the array in descending order and pick its first and second elements. In this method, what we do is that we compare the index of all the items of an array with the index of the first time that number occurs. We can find the second largest number in an array in java by sorting the array and returning the 2nd largest number. Initialize the accumulator using an empty array and at every iteration check if the current value is greater than num then concatenate the current value with the accumulator and return it otherwise return the accumulator as it is. var secondMax = function () { var arr = [20, 120, 111, 215, 54, 78]; // use int arrays var max = Math.max.apply (null, arr); // get the max of the array arr.splice (arr.indexOf (max), 1); // remove max from the array return Math.max.apply (null, arr); // get the 2nd max }; View . The greatest common divisor (GCD), also called the highest common factor (HCF) of N numbers is the largest positive integer that divides all numbers without giving a remainder. Find the index of the array element you want to remove using indexOf, and then remove that index with splice. var secondMax = function () { var arr = [20, 120, 111, 215, 54, 78]; // use int arrays var max = Math.max.apply (null, arr); // get the max of the array arr.splice (arr.indexOf (max), 1); // remove max from the array return Math.max.apply (null, arr); // get the 2nd max }; View . Question: Given an array of integers, find the highest product you can get from two of the integers.
