A WaitGroup waits for a collection of goroutines to finish. The main goroutine calls Add to set the number of goroutines to wait for. Then each of the goroutines runs and calls Done when finished. At the same time, Wait can be used to block until all goroutines have finished. 大意为...

wg.Wait() // Wait for all goroutines to finish } Explanation: This program uses Go's goroutines for parallel computation. The sync.WaitGroup ensures all goroutines complete before the program exits. Why Choose Rust Over Go? You need maximum performance and memory safety. ...
