Challenge #130: Is There an Echo in Here?

I am no expert just yet, I used multiple tools to identify the duplicate words, and then output phrase without the duplicate.

I will now to see other people solution for that tool that does this.

Here's a couple of interactive sites to help you learn

 

https://regex101.com/

https://regexr.com/

 

Both of them allow you to build and test your regex against strings that you input.  They also try to explain what your expression is doing and what its parts are.

Finally got it with one tool.

Will have to apply more regex in my future workflows.

This is most certainly not the best way to do this, but it gets the job done.  Sort of, anyway.  I made it work regardless of capitalization, but I don't think it would work if one of the repeated words was followed by punctuation.

Now that I've posted my solution, I've definitely got to go check out how an advanced user did it in one tool.  (I'm guessing it's a really complicated regex, and that's definitely not my strong suit.)
