如何使用默认排序功能在Golang中对整数数组进行排序

A stupid question. I can't sort using default sort function in go

    package main
    import "fmt"
    import "sort"
    func main(){
            var arr [5]int
            fmt.Println("Enter 5 elements")
            for i:=0;i<5;i++{
                    fmt.Scanf("%d",&arr[i])
            }
            sort.Ints(arr)
            fmt.Println(arr)
    }

When executing the above program, It throws out

cannot use arr (type [5]int) as type []int in argument to sort.Ints

Need Help.
