I thought I was done after the first hour until I ran CCC’s test cases. Turns out I lacked a SINGLE but necessary test case that I didn’t write.

This is much more interesting case study of TDD and how skipping a step ahead can mess you up tremendously.

Summary of Zero That Out: Positive integers are provided from input one at a time. Every input that is a 0 ignores the last given input (a series of n 0s means ignore the last series of n inputs). The program should keep track...

Given a bunch of items, their price per item, and a special bulk discount rate: create a system that can add items to your basket and a checkout system that can scan your basket and output the final price, taking the bulk discount rate into consideration. (i.e. item A cost...
