Answer 1

package main

import (
    "fmt"
)

func main() {
    // Initialize a slice equivalent 
    arr := []int{1, 2, 3, 4, 5}

    // Check if the slice is not empty
    if len(arr) > 0 {
        // Remove the first element
        arr = arr[1:]
    }

    // Print the updated slice
    for _, num := range arr {
        fmt.Print(num, " ")
    }
}
