Welcome! Today, I am excited to guide you through a fascinating task involving lists in Kotlin: pairing up 'opposite' elements. Specifically, we're going to learn how to access and manipulate elements within a Kotlin List. This task provides an excellent opportunity to elevate your list-handling skills using the Kotlin language. Are you ready to get started? Let's dive right in!

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

You will be provided with a List of n integers, where n could range from 1 to 100, inclusive. The task requires you to return a List of String objects. Each String consists of an element and its 'opposite' element joined by a space.

Let's use the example list numbers as to simplify our understanding. In this case, the output of our function will be .
