Programming Challenge: Launch 4 threads, goroutines, coroutines, or whatever your language uses for concurrency, in addition to the main thread. In the first 3, add numbers together (see sample code below) and pass the results to the 4th thread. That 4th thread should receive the 3 results, add the numbers together, format the results as a string (see sample code), and pass the result back to `main` to be printed.
Do this as succinctly and readably as possible. _Go!_ #golang #programming #concurrency #challenge
