reverseconcatalternate

Instructions

Write a function that receives two slices of int as arguments and returns a new one with the result of alternating the values of each in reverse order.

• The input slices may be of different lengths.
• The new slice should contain the elements of the larger slice first and then the elements of the smaller slice.
• If the slices are of equal length, the new slice should contain the elements of the first slice first and then the elements of the second slice.
• The new slice should be in the reverse order of the input slices.

Expected function

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

Usage

Here is a possible program to test your function :

package main

import (
	"fmt"
)

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

And its output :

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