Probably the solution involved tinkering with the registers a little, but not so bluntly

Got it, didn't read the assignment carefully

Given a list of integers and a single sum value, return the first two values (parse from the left please) in order of appearance that add up to form the sum.

The Kata specifications outline the behavior that makes your current interpretation invalid, since the paired numbers 3 and 7 appear to the right of an alternate complete pair. Try a new solution that follows that spec!

Wrong task. We are looking for the nearest two pairs. Fine. [10, 5, 2, 3, 5, 7], 10) - here is a test that all correct solutions fail. Correct answer: [3,7]
