Example of Absolute use

Today we discuss Absolute

To return a number here is a very complicated task because a number of iterations is limited (if we try to solve it with arrays). Instead we can use string literals and return a string as a result.

Here we go 🚀

Return result for the string

If we have a string, and we know that there's a number in it, we can check for a minus sign at the beginning:

Positive in case we have negative
Positive in case we have negative

Otherwise, we return the same string as we expect it to be positive

Return result for the number and bigint

Still we return the same number or bigint if we pass it to Absolute

As we already can manipulate numbers in a string, let's put a number to a string:

Put number and bigint into a string
Put number and bigint into a string

And now all the tests are passed ✅ –

Good night ⛈🌙
