👉 Skeletonising is a process in computer science where you add a new variable to an existing list, without changing its contents. This can be useful for simplifying code and reducing complexity. A common use case of skeletonizing is in algorithms that involve sorting or searching. For example, if you have a list of integers and you want to sort them in ascending order, you could use the built-in `sort()` function with a custom comparator function. If you don't need to change the original list's
