Question: Can you write code implementing the consumer and producer pattern?
This is a classic concurrency problem where we have threads generating data to be consumed (producers) by other threads (consumers).
The implementation with POSIX threads can be a pain in the ass but it is quite straight forward in golang thanks to its concurrency constructs.
