Wow, this one was super fun.
First, I started out with some investigation of the data from Challenge 155:
* Oddly enough, the A (capital A, code 65) did not occur at all in the challenge 155 data??
* For each position within the string, the correct character occurred in that position about 5x as frequently as any other character (for example, character 1 was the correct character about 5% of the time, while other characters occurred about 1% of the time)
Finally, example output:
I remember challenge (#155) and that was fun.
This one was tough though, so my solution ain't pretty, but I got to the result in the end
You solved it! You shared it! We all learn!
I've gotta admit I've learned and improved my solution based on other solutions as well!
It's what makes Alteryx Community great!!! <3
