Instructions

Write a function ConcatAlternate() that receives two slices of an int as arguments and returns a new slice with the result of the alternated values of each slice.

• The input slices can be of different lengths.
• The new slice should start with an element of the largest slice.
• If the slices are of equal length, the new slice should return the elements of the first slice first and then the elements of the second slice.

Expected function

func ConcatAlternate(slice1,slice2 []int) []int {

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
)

func main() {
	fmt.Println(ConcatAlternate([]int{1, 2, 3}, []int{4, 5, 6}))
	fmt.Println(ConcatAlternate([]int{2, 4, 6, 8, 10}, []int{1, 3, 5, 7, 9, 11}))
	fmt.Println(ConcatAlternate([]int{1, 2, 3}, []int{4, 5, 6, 7, 8, 9}))
	fmt.Println(ConcatAlternate([]int{1, 2, 3}, []int{}))
}

And its output:

$ go run .
[1 4 2 5 3 6]
[1 2 3 4 5 6 7 8 9 10 11]
[4 1 5 2 6 3 7 8 9]
[1 2 3]
