Glad you liked it. If theres a specific challange you want out there, you should try authoring something yourself :)

Thank you. Very nice kata. Learned how to scrap wiki. Would like more katas with real life problems instead of restricted with specific algorithms <3

trash kata. use si system units next time. Nobody have time to figure out how this magic units works.

Solved with simple brutforce.

Add larger numbers and more random test

china_time = {0:'子',1: '丑',2: '寅',3: '卯',4: '辰',5: '巳',6: '午',7: '未' ,8:'申' ,9:'酉', 10:'戌',11: '亥',12:'子'}

I solved with silple brutforce after summation step :)

I spoiler it, this would made it a 8 kyu, and it is the key and simple thing to solve in this kata.

The requirement was unintuitive to me at least and isnt clearly explained anywhere in the description.

@KayleighWasTaken yes, they are, but because w or l is zero... well, these two walls form a 2D rectangle, and since there is zero width of it...

Anyways, for the simplicity, one may say it's zero if any of these variables are zero imho
