Write an Elixir function to solve each of the problems below. Each function will accept a list as input and return either a Boolean value or another list, depending on the question. For this part of the lab, you may not use branching or repetition of any kind. No recursion, no if/else, no indexing. Head and tail will serve you well here.

1) isCoordinate Return True if the input list could represent a coordinate otherwise return false. A coordinate has two elements and they are both numbers.

2) helloIfSo If the input list contains the string Hello, remove it and place it at the end of the list. If it does not contain Hello, add it to the end of the list.
