如何在Go中的动态通道列表中选择输入？

package main

import (
	"fmt"
	"time"
)

func main() {
	channels := make([]chan int, 3)
	for i := range channels {
		channels[i] = make(chan int)
	}

	go func() {
		for i := 0; i < 3; i++ {
			channels[i] <- i
		}
	}()

	for i := 0; i < 3; i++ {
		select {
		case value := <-channels[0]:
			fmt.Println("Received from channel 0:", value)
		case value := <-channels[1]:
			fmt.Println("Received from channel 1:", value)
		case value := <-channels[2]:
			fmt.Println("Received from channel 2:", value)
		}
	}

	time.Sleep(1 * time.Second)
}
