Great kata, awesome description, thanks! :)

the only guy having fun here :) tried similar stuff, but gave up...

great kata, thanks! learned something new :)

great kata, worst description ever though

little hard, but very very good kata, thanks!

description probably should specify there will be only integer numbers in test cases

first top voted solution that is really cool in a while

though i came to the conclusion that it was my flawed interpretation at the end, the description indeed is clearer now, thanks!

so what? lets say you have for instance [3, 4, 3, 3] instead
so last two 3's are mutual duplicates of each other, therefore first 3 has no duplicate.
cant it be interpreted like that, or it's just me? :)
maybe i should look into "duplicate" definition, idk...

maybe the description could be more clear - you could say "ignore numbers that appear more than once in array"

i thought sum of array [ 1, 10, 3, 10, 10 ] should ignore only last two 10's, and not the first one, cuz it technically might not be a duplicate

anyways, had fun! (mostly cuz of me misunderstanding the task)

this is oddly satisfying :)

just tested 'wqqq' case. indeed it fails.

LOL WTF :)
