Implement a function that reads numbers in from a file with one number per line and outputs all the possible sums that can be formed by subsets of the numbers. For instance, if the numbers in the file are 1 2 4, then the output would be 0, 1, 2, 4, 3, 5, 6, 7. Note that O is in the output because it uses none of the numbers, while 7 is the sum of all of the numbers. // Return all sums that can be formed from subsets of elements in arr public static ArrayList allSums( ArrayList arr ) { ... }
