Part 1 , Part 2 , Part 3 , Part 4 , Part 5 Return values from go routines cannot be captured in the usual way with the = operator because starting a go routine is non blocking. A channel can be used to collect the results from many concurrent go routines. Write a value to a channel inside the go routine that is doing the work, then in main() read from the channel until it is closed to collect all the results from the go routines....
Part 1 , Part 2 , Part 3 , Part 4 , Part 5 Goroutines can be used to take advantage of CPUs with multiple processors. Starting a Goroutine using the “go” keyword, will start execution on a thread in parallel if a thread is available. You will need to make sure that your main function does not exit before all the goroutines finish their work. Playground: https://go.dev/play/p/FTJLzwY34l2 package main import ( "fmt" "sync" ) func main() { wg := sync....
