Go语言冒泡排序实现代码

    package main  
      
    import (  
        "fmt"  
    )  
      
    func main() {  
        A := []int{5, 21, 2, 4, 1}  
        num := len(A)  
        for i := 0; i < num; i++ {  
            for j := i + 1; j < num; j++ {  
                if A[i] > A[j] {  
                    A[i], A[j] = A[j], A[i]  
                }  
            }  
        }  
        fmt.Println(A)  
    }
