Instructions

Write a function RevConcatAlternate() that receives two slices of int as arguments and returns a new slice with alternated values of each slice in reverse order.

• The input slices can have different lengths.
• The new slice should start with the elements from the largest slice first and when they became equal size slices, it should add an element of the first given slice.
• If the slices are of equal length, the new slice should start with an element of the first slice.

Note: you can check the examples bellow for more details.

Expected function

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

}

Usage

Here is a possible program to test your function:

package main

import (
	"fmt"
	"piscine"
)

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

And its output:

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