Implementation Tasks

Alex Chen55 min readUpdated

Each task here comes with a story, some from exchange plumbing and some from plain everyday logic. The algorithm under each one is short. Most of the work is in the rules, and the hidden tests check them one branch at a time, so code that skips a rule fails even when the main path works.

Two of them borrow their rules from exchange plumbing, with priority and tie rules that decide who gets what. The other two are plain logic with a lot of cases. In every one, the rules take more code than the algorithm.

Write each rule as a small helper, and test it alone before you wire the helpers together. Where a rule could be read two ways, like a tie rule, ask your interviewer which version they want.
