Lesson Overview

Welcome! Today, I am thrilled to guide you through a fascinating task involving arrays in TypeScript: pairing up "opposite" elements. Specifically, we're going to learn how to access and manipulate elements within a TypeScript array. The task at hand provides an excellent opportunity to elevate your array-handling skills within TypeScript. Are you ready to get started? Let's dive right in!

Task Statement and Description

Our task today is to form pairs of "opposite" elements in a given array of integers. In an array consisting of n elements, the first and last elements are known as "opposite," the second element and the second-to-last element are considered "opposite," and so on. For an array with an odd length, the middle element is its own "opposite."

You will be provided with an array of n integers. The value of n could range from 1 to 100, inclusive. The task will require you to return an array of strings. Each string will consist of an element and its "opposite" element joined by a space.

Let's use the example array numbers as [1, 2, 3, 4, 5] to simplify our understanding. In this case, the output of our solution(numbers) function will be ["1 5", "2 4", "3 3", "4 2", "5 1"].
