Generate Random Number in Slice in Golang

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func RandomSlice(n int) []int {
    slice := make([]int, n, n)
    rand.Seed(time.Now().UnixNano())
    for i := 0; i < n; i++ {
        slice[i] = rand.Intn(9999) - rand.Intn(9999)
    }
    return slice
}

func main() {
    fmt.Println(RandomSlice(6))
    fmt.Println(RandomSlice(20))
}
