Yeah mine does that a lot too. Something about pasting code into the editor you wrote in something else seems to destroy the indentation.

Yes, often you'll see 1/0 replaced for true/false when someone is using binary to store some boolean values.

Think of what other values can be usually interchanged for true/false

Thanks. That is indeed bitchin!

Well I just was pointed out a critical flaw in the way my solution works. It passes all the tests, but in doing so I'm actually mutating the original arrays unwittingly.

Perhaps you could add tests that make sure the original arrays aren't modified.

My solution is written very long and verbose compared to the top one , but it made me feel a bit better when mine seemed to be much faster.

How do you guys get so good at compressing things into such compact code :D

Wow, I did it :D

I'm not sure how I've made it to the 5 kyu rank. But somehow my spaghetti worked to solve this, lol.

lol I know what you mean.

This one hurt my brain lol. I feel like I learned alot in the process though.
