Go语言排序与接口实例分析

import "fmt"
type Sorter interface {
  Len() int
  Less(i,j int) bool
  Swap(i,j int)
}
type Xi []int
type Xs []string
func (p Xi) Len() int { return len(p) }
func (p Xi) Less(i int,j int) bool { return p[j] < p[i] }

func (p Xs) Len() int { return len(p) }
func (p Xs) Less(i int,j int) bool { return p[j] < p[i] }
func (p Xs) Swap(i int,p[i] }
