title: Find Possible addition combinations in array
body: <p>What is the best way to approach this problem? I have no idea on how to start. This is not a homework problem, but rather practice for interviews.</p>
  
  <p>'Using the JavaScript 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. '</p>
