#Get the averages of these numbers
Write a method, that gets an array of integer-numbers and return an array of the averages of each integer-number and his follower, if there is one.
Example:
Input: [ 1, 3, 5, 1, -10]
Output: [ 2, 4, 3, -4.5]If the array has 0 or 1 values or is null or None, your method should return an empty array.
Have fun coding it and please don't forget to vote and rank this kata! :-)
