Challenge #130: Is There an Echo in Here?

[papalow]

Agreed.  Seeing other solutions after you have found the long way to solve the challenge is a good thing.

I figured the one tool solution would be a regex, but didn't want to spend the time working through the pattern. Let's just make it needlessly complicated instead.

I also used regex...

Set phaser parser to Replace.
RegEx

(.*)(\b[A-z']+)(\s\2)(.*)

Replace it with

\1\2\4

Wow I just finished my RegEx crush course and here comes the challenge!

Spent around 30 minutes but it's very worthwhile.

Reminds me of the joke:

I have a problem. I know I should use RegEx.

Now I have two problems.

Great challenge! I found 2 different "1-tool solutions". OK, they're the same thing, but still good practice and I learnt something new!

My solution, not the one tool solution.
