remove an element from the beginning of an array in go

To remove an element from the beginning of an array in Go, you can convert the array to a slice, remove the first element from the slice, and then convert it back to an array if necessary.

Here's an example:

main.go
package main

import "fmt"

func main() {
    // create an array
    arr := [4]int{1, 2, 3, 4}

    // convert array to a slice
    slice := arr[:]

    // remove first element from the slice
    slice = slice[1:]

    // convert slice back to an array
    arr = [4]int{}
    copy(arr[:], slice)

    fmt.Println(arr) // output: [2 3 4 0]
}

In this example, we first create an array with 4 elements. We then convert the array to a slice, remove the first element from the slice, and copy the remaining elements back to an empty array. The resulting array contains the same elements as the original array, except for the first element which has been removed.
