Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Not a great one imo. Some of these math ones the problem is just in googling "conversion of x to y" then copying it and pasting it into the ide.
Yeah I agree. But is is easy if u know the formula... But programming is also math, so not bad for google practice. :).
See ones like this being marked easy is kinda silly because you either know the formula and get it in one or you don't and its a pain. This isn't really testing your programming knowledge at all and testing how good you are at Mathematics
