+
+Given a string of digits confirm whether the sum of all the individual even digits are greater than the sum of all the individual odd
+digits. Always a string of numbers will be given.
+
+* If the sum of even numbers is greater than the odd numbers return: `"Even is greater than Odd"`
+
+* If the sum of odd numbers is greater than the sum of even numbers return: `"Odd is greater than Even"`
+
+* If the total of both even and odd numbers are identical return: `"Even and Odd are the same"`
