是否可以在处理时向Go频道添加项目？

Question

我正在尝试找到一种使用goroutines递归地完成Go任务的方法。该程序的目标是将一个输入元素带入一个通道，并添加到输出通道输入-1，直到达到0。加工工人的数量应适应。我正在遵循的过程是这样的：

创建输入和输出通道。将起始编号添加到输入通道。初始化工作程序以运行工作程序功能。循环浏览并在输出通道中打印输出。

func main() {
    inputChannel := make(chan int, 1)
    outputChannel := make(chan int)
    inputChannel <- 100
    numWorkers := 4
    for i := 0; i < numWorkers; i++ {
        go worker(inputChannel, outputChannel)
    }
    for elem := range outputChannel {
        fmt.Println("Output: ", elem)
    }
}

接下来，在order函数中，我们遍历输入通道中的元素，每次检查是否还有更多元素要接收。如果要接收的元素更多，我们将打印输入元素，从元素中减去1，然后发送到输入通道，以供其他工作人员在元素大于0时使用。如果输入通道中没有剩余内容，则我们返回。

func worker(input chan int, output chan<- int) {
    defer close(input)
    defer close(output)
    for {
        element, more := <-input
        if more {
            fmt.Println("Input: ", element)
            element--
            if element != 0 {
                input <- element
            }
        } else {
            fmt.Println("All Jobs Processed")
            return
        }
    }
}

我看到的输出是：

我已经尝试过多种方式来依赖于像这样的渠道并使用等待组，但是我似乎无法使该过程遍历所有项目并发出输出。
