Question

Given an array of strings, I want to change every string into a string that is composed of the original letters from the original string sorted alphabetically.

So, given an array:

words = ["apple", "orange"] 

the method should return:

["aelpp", "aegnor"]

---

While using:

words[0].chars.sort(&:casecmp).join

returns the desired string in the array, so I have tried to use:

words.each {|y| y.chars.sort(&:casecmp).join }

but this returns the array in its original state.

I am learning Ruby as we speak and do not understand why this doesn’t work.

Answer 1

I needed to use the following:

words.map {|y| y.chars.sort(&:casecmp).join }

Because I wanted to transform my original array into another array.
