How can two arrays or lists be combined into one?

In Go, to combine two slices, you can use the built-in append function. It allows you to add all elements of one slice to another.

Example of combining two slices:

package main

import "fmt"

func main() {
    a := []int{1, 2, 3}
    b := []int{4, 5, 6}

    c := append(a, b...)
    fmt.Println(c) // Output: [1 2 3 4 5 6]
}

Here, b... is the syntax for unpacking the slice b into individual elements for the append function.

For arrays, you first need to convert them into slices, then combine using append.
