    I disagree with both of you. As you can see 1675 people solved this kata. So it seems, that they understood the instructions.

    To solve a kata does not mean, to type the description of the kata in a computer language! It is thinking, trying, tranforming and testing. This kata is not so hard to understand.

    I completely agree. Every time I thought I had solved the exercise it turned out there was another edge case I hadn't accounted for. On top of that the first initial test cases are all arrays of arrays so I thought I had solved this relatively quickly. It's frustrating when the difficulty in a problem is not the problem itself rather stumbling through the poor instructions.
