go 切片排序以及转为带间隔符的字符串

package main
import (
  "sort"
  "fmt"
  "strings"
)
func main() {
  // 切片排序
  intSlice := []int{
    1, 3, 4, 2, 55,
  }
  sort.Slice(intSlice, func(i, j int) bool {
    return i > j
  })
  fmt.Println(intSlice)
  // 切片嵌套字典排序
  result := []map[string]interface{}{
    {"sort_time": 1},
    {"sort_time": 2},
  }
  sort.Slice(result, func(i, j int) bool {
    return result[i]["sort_time"].(int) > result[j]["sort_time"].(int)
  })
  fmt.Println(result)
  // 将切片转为,号分割的字符串
  strSlice := []string{"a", "b", "c"}
  strJoin := strings.Join(strSlice, ",")
  fmt.Println(strJoin)
}
