and I saw it this morning in just one of my attempts

4 years later still there rip

Please use spoiler flag next time.

Added sample tests

It's 6 Kyu if you know Regex.

i dont understand what you're talking about, this kata has no random tests, let alone performance tests. you must have posted on the wrong page ^^

My hunch is that all new katas are likelier to be solved first by Top100 peeps who have basically solved all the other ones already and who
tend to underestimate the kata's difficulty to us mere mortals. I've seldom seen an easy kata given a higher kyu but quite often the opposite.

nah this is definitely a 6

As you need to return to the starting point and you can only move in cardinal directions, its just a logical step that for each move west, you must move the same amount east, as the other two directions cannot get you back to 0 on the x axis.

I completely agree

I'm getting the same error in Ruby, all the tests have passed but I get this similar exit code
main.rb:24:in `rescue in block (2 levels) in <main>': undefined method `twoSum' for main:Object (NoMethodError) Did you mean? two_sum too

I got that twoSum error too with Ruby. I've printed it out below. Mine passed about 8 tests before failing this one.

main.rb:37:in rescue in block (2 levels) in <main>': undefined method twoSum' for main:Object (NoMethodError)
Did you mean? two_sum

Part of me wonders if a test has twoSum as one of the method calls most likely me that's made the mistake though :-)

Personally I like things to be kept implicit whenever possible so long as they are unambiguously deducable from what is already said.
Which it is.
And anyone assuming anything else would be wrong to do so because the description would not support their assumption, they would be making that up.
