Golang实现插入排序

package main

import (
    "fmt"
)

func main() {
    var arr []int
    arr = []int{3, 4, 9, 6, 7, 1, 2}
    res := iSort(arr)
    fmt.Println(res)
}

func iSort(arr []int) []int {
    var tmp int
    count := len(arr)
    for i := 1; i < count; i++ {
        for j := i; j > 0 ; j-- {
            if arr[j-1] > arr[j] {
                tmp = arr[j-1]
                arr[j-1] = arr[j]
                arr[j] = tmp
            }else {
                break
            }
        }
    }
    return arr
}
