如何修改下述代码使其不会报deadlock（使用管道）

//要求：1.将1~2000个数放入一个ch中 2.启动8个协程读取该ch，并计算1~n之和写入reschan中 ```go func InitNum(ch chan int) { for i := 1; i <= 2000; i++ { ch <- i } close(ch) } func readNum(ch chan int, reschan chan map[int]int, remap chan bool) { for { temp, ok := <-ch if !ok { break } else { res := 0 remp1 := make(map[int]int) for i := 1; i <= temp; i++ { res = res + i } remp1[temp] = res reschan <- remp1 } } } func readMap(reschan chan map[int]int, remap chan bool) { for { temp, ok := <-reschan if !ok { fmt.Println("readMap break") break } else { fmt.Println(temp) } } remap <- true close(remap) } func main() { ch := make(chan int, 2000) reschan := make(chan map[int]int, 2000) remap := make(chan bool, 8) for i := 0; i < 8; i++ { go readNum(ch, reschan, remap) go readMap(reschan, remap) } go InitNum(ch) for i := 0; i < 8; i++ { <-remap } } ```
