We are required to write a JavaScript function that takes in two arrays of numbers of the same length. The function should return an array with any arbitrary nth element of the array being the sum of nth term from start of first array and nth term from last of second array. For example...
When working with arrays in JavaScript, one common task is calculating the sum of all the numbers contained within that array. Whether you’re developing a web application, analyzing data, or just experimenting with code, knowing how to efficiently sum an array can save you time and effort. ...
of using streams: compare the following code to return the names of dishes that are low in calories, sorted by number of calories, first in Java 7 and then in Java 8 using streams. Don’t worry about the Java 8 code too much; we explain it in detail in the next sections! 1. 2. ...

Arrays.sort(nums); int result = 0; for (int i = 0; i < nums.length-2; i++) { int left = i+1; int right = nums.length-1; int cur = nums[i]; while (left < right) { int two_sum = nums[left] + nums[right];

Every element arr[i] appears in two types of subsets: i) In sybarrays beginning with arr[i]. There are (n-i) such subsets. For example [2] appears in [2] and [2, 3]. ii) In (n-i)*i subarrays where this element is not ...
