# Write a method that takes an array of numbers in. Your method should
# return the third greatest number in the array. You may assume that
# the array has at least three numbers in it.
#
# Difficulty: medium.

  sorted_nums=nums.sort

  return sorted_nums[nums.length-3]
end

# These are tests to check that your code is working. After writing
# your solution, they should all print true.
