-## Concat-Alternate
-
+## concatalternate
 
 ### 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.
-- 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.
+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 return 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 return the elements of the first slice first and then the elements of the second slice.
 - The new slice should be in the same order as the input slices.
 
 ### Expected function
 
 ```go
 func ConcatAlternate(slice1,slice2 []int) []int {
-    
+
 }
 ```
 
 ### Usage
 
-Here is a possible program to test your function :
