func sortColors(nums []int)  {sort.Ints(nums)
}

tips

package mainimport ("fmt""sort"
)//定义interface{},并实现sort.Interface接口的三个方法
type IntSlice []intfunc (c IntSlice) Len() int {return len(c)
}
func (c IntSlice) Swap(i, j int) {c[i], c[j] = c[j], c[i]
}
func (c IntSlice) Less(i, j int) bool {return c[i] < c[j]
}
func main() {a := IntSlice{1, 3, 5, 7, 2}b := []float64{1.1, 2.3, 5.3, 3.4}c := []int{1, 3, 5, 4, 2}fmt.Println(sort.IsSorted(a)) //falseif !sort.IsSorted(a) {sort.Sort(a) }if !sort.Float64sAreSorted(b) {sort.Float64s(b)}if !sort.IntsAreSorted(c) {sort.Ints(c)}fmt.Println(a)//[1 2 3 5 7]fmt.Println(b)//[1.1 2.3 3.4 5.3]fmt.Println(c)// [1 2 3 4 5]
