[1] int {}和[] int {0}有什么区别

I'm trying to get array changed in other func, and then return the changed. So I wrote a sample code below, my question is why changes in changeArr02 function can affect the origin arr while changeArr01 not.

package main

import "fmt"

func changeArr01(arr [1]int) {
        arr[0] = -100
}

func changeArr02(arr []int) {
        arr[0] = -200
}

func main() {
        arr01 := [1]int{}
        changeArr01(arr01)
        fmt.Println(arr01) // 0

        arr02 := []int{0}
        changeArr02(arr02)
        fmt.Println(arr02) // -200
}

 arr01 := [1]int{}

is an array of integer with the size of 1

 arr02 := []int{0}

it's a slice of ints with one integer inside (0)
