Welcome! Today, I am excited to guide you through an intriguing task involving arrays: pairing up 'opposite' elements. We're going to learn about accessing and manipulating elements in Python arrays. This task provides an excellent opportunity to refine your array-handling skills in Python. Are you ready to start? Let's dive right in!
Our task is to form pairs of 'opposite' elements in a given array of integers. In an array of n
elements, we view the first and last elements as 'opposite', the second and second last elements as 'opposite', and so on. If the array length is odd, the middle element is its own 'opposite'.
You are provided with an array of n
integers, with n
ranging from 1 to 100, inclusive. The task necessitates that you return an array of tuples, where each tuple comprises a pair of an element and its 'opposite' element.
For example, for numbers = [1, 2, 3, 4, 5, 6, 7]
, the output should be:
Before we start writing code, let's familiarize ourselves with how to access the elements of an array in Python.
In Python, the i
-th element of an array numbers
can be accessed as numbers[i]
, with the index starting from . Consequently, the first element can be accessed using , the second using , and so forth, up to for the last element.
