One-line Kata)

Really great for learning how to calculate multplies, it's a great 'aha!' moment.

agreed

doubt yours is uglier than mine. haha

That is to give the ASCII-ART the trianglular space / representation. Surely, this is not the only ASCII-ART kata that expects leading spaces !

I disagree with this being 8kyu, this is more like 7-6ish. Plus the description lies to you about what will be tested.

pretty much the ugliest coding you can imagine, but got it to work in the end.

seem to have another instance of groovy random tests failing even though the actual tests pass

Random tests
assert sumMul(n, m) == sol(n, m)
       |      |  |  |  |   |  |
       |      53 |  |  |   53 721689
       618373112 |  |  4913340408
                 |  false
                 721689

yup!

Approved

python new test framework is required. updated in this fork

Your code fails for cases like n = 2, m = 2 whereby the correct answer is 0, but your code returns INVALID

Your code regarding summation is wrong although it passes all random cases

He says spaces between the digits but doesn't say spaces before the digits. But in the sample tests it looks like there is a space before the ones. What the heck? Very confused about the spacing here. I put 0 space on each side of digits and increment the spaces by 1 as line breaks are added but that doesnt seem to work. Whats the deal with the spacing?
