Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Why wouldn't you use a built in method?
What I mean, is if you get this during an interview, you probably whould need to show how it's done without the build-in methods.
isn't it the best practice?

agree, haven't taken the complexity into consideration while solving the task
sorting the array is wasteful time for this task.
we need to calculate only the difference between max and min values.
finding max and min can be done in O(n) while sorting array with
sort will take in worst case nlogn
note that this mutates the input, which is pretty bad practice.
