Strings, Lists and Grids

Jump's coding problems also include three classics with no trading story, from Codility tests, a research-track round and a campus round.

All three come down to careful bookkeeping. A precomputed table has to be exact, every pointer has to be saved before you overwrite it, and the bit order has to be right before you start searching.

Each problem below has its own tests in six languages. One task left its output format open, so ask your interviewer what they want back.
