Go語句實現簡單的冒泡排序

demo

package main

import "fmt"

func main()  {
    arr := [...]int{6, 8, 9, 5, 7, 3, 4, 2}

    arr_len := len( arr )

    fmt.Println( "冒泡排序之前：", arr )
    for i := 0; i < arr_len ; i++  {
        for j := i + 1; j < arr_len; j++ {
            if arr[i] > arr[j] {
                tem := arr[i]
                arr[i] = arr[j]
                arr[j] = tem
            }
        }
    }
    fmt.Println( "冒泡排序之後：", arr )
}

res

冒泡排序之前： [6 8 9 5 7 3 4 2]
冒泡排序之後： [2 3 4 5 6 7 8 9]
