In this round you will implement four small Python routines. Two of them consume a sequence of events or numbers, one aggregates nested records, and one constructs a new string. Aim for clean, efficient implementations; the required imports and type hints are shown with each task. Each task below states its contract, the guarantees you may rely on, and a few worked samples. Return exactly the value described — no printing, no extra output. Task 1 You are given a list scores…
