hist[val] {

Hi, I think you need to test hist[val] == 2 because it will be trivially set to 1
on each line... at least this is what my awk thinks!

Honestly, I don't even remember what I was thinking, but...

1. I am certain that it worked, since the result passed
2. hist[val] == 2 is always false, since hist[val] is only set to 1.

You're right 2 doesn't make sense..
I see I have hist[val] += 1 instead of hist[val] = 1, this is why it works with 2 for me.
