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.
Get started now by creating a new collection.
For C there is a test with count == 0, but the instruction was clear "the array can't be empty".
To be honest for x, x, x I had no idea what is better to put except for 1, 1.
For other cases I think I'll put condition in description that concentrations are from 1 ot 100%.
Random tests are honestly generated by random function :) But I got your point.
Did you ever read the description?
You have two source solutions concentrations and one target concentration. You need to calculate amounts to mix to obtain solution with target concentration. Amounts are integer numbers simplified to lowest possible terms, so instead of answer like (100, 50) you should provide (2, 1).
Fixed. Thanks!
