Kuidas teha kahe worker() täitmine paralleelselt asemel järjestikuna (6 sekundit → 3 sekundit)?

In Go, functions can be executed in parallel using goroutines. If you have two worker() functions that are currently executed sequentially and take a total of 6 seconds, launching them in separate goroutines will run them in parallel, reducing the total time to approximately 3 seconds.

Example:

func() {
    worker()
}()
func() {
    worker()
}()

// To wait for both goroutines to finish, use sync.WaitGroup
var wg sync.WaitGroup
wg.Add(2)
func() {
    defer wg.Done()
    worker()
}()
func() {
    defer wg.Done()
    worker()
}()
wg.Wait()

This way, launching functions in goroutines and synchronizing them with WaitGroup allows their parallel execution.
