Go语言map排序

package main

import (
	"fmt"
	"sort"
)

func main() {

	// map排序
	// 1.先将map的key放到切片中
	// 2.对切片进行排序
	// 3.遍历切片，然后按照key来输出map的值
	map1 := make(map[int]int,10)
	map1[10] = 100
	map1[1] = 13
	map1[4] = 56
	map1[8] = 90

	fmt.Println(map1)

	var keys [] int
	for _, k := range map1 {
		keys = append(keys, k)
	}
	sort.Ints(keys)

	for _, k := range keys {
		fmt.Printf("map1[%v]=%v\n", k, map1[k])
	}
}
