Problem

A Semaphore caps how many fetches run at once. You have 10 fetches, each taking 1.0s of wait, and a concurrency limit of 3. They run in waves of at most 3; total time = number_of_waves * 1.0s. Compute and print the number of waves and the total seconds (1 decimal), one per line. (Model it, no asyncio.)
