Functions

func Int32

func Int32(n int32) int32

func Int64

func Int64(n int64) int64

func Random

func Random(min, max int32) int32

func RandomNum

func RandomNum(min, max, num int32) []int32

给定一个范围，随机若干个数

func RandomQSlice

func RandomQSlice(list interface{}, num int32, canRepeated bool) interface{}

从一个slice里面，根据权重，随机出value

可以重复的参数比不可重复效率略高

list := []struct{int32,interface{}}

切记不要修改返回值里面的内容
