you gotta be joking

I've just tried a pair of naive solutions from the 7kyu and they don't pass a single large test. Sometimes they don't pass on the medium ones. I think it's ok, isn't it?

Well, there is not 3 kyu :D You mean the 7kyu?

(edited)
You mean one for the 3 kyu?

are you sure the basic algo cannot pass by chance?

That jump() function is really simple and clever!

Getting odds and evens swapped? Your list has 2,3,4,5,6 appearing odd number of times, the kata states there will be exactly one that appears an odd number of times. And yes, this trick only works if the input follows the rule.

I've tested this solution out, and if we give a list like [1, 1, 2, 3, 4, 5, 6], I get back 6. If I give it the list [1, 1, 2, 3, 4, 5], I get back 0.

It's not avaiable in Rust 1.15

@newmaidumosa sorry for long reply. that's good question, but i've never used it before. you can define them directly
