+"""
+Using the Python language, have the function ArrayAddition(arr) take the array
+of numbers stored in arr and return the string true if any combination of numbers
+in the array can be added up to equal the largest number in the array, otherwise
+return the string false. For example: if arr contains [4, 6, 23, 10, 1, 3] the
+output should return true because 4 + 6 + 10 + 3 = 23. The array will not be
+empty, will not contain all the same elements, and may contain negative numbers.
