Try the challenge on CodeWars first – and then have a look at my solution which is mainly based on this challenge.
What did I learn from this?
Well, I worked out that using a HashMap was a neat way to identify the gap that was different to the others.
What else?
Starting from 1 and iterating up to sequence length minus one is the way to stop out of bounds error. (line 29)
