A better way is to just "partial.add(n)" do the recursion and then "partial.remove(partial.size -1). lottery numbers) 4 (~ 4.0) If order matters (e.g. Here is a solution that is O(size_of_array * (number_of_sums + number_of_solutions)). To be as useful as possible, the code should return a List[List[Int]]in order to allow getting the number of solution (length of the list of lists), the "best" solution (the shortest list), or all the possible solutions. $125.96 And the entry for 5 reads, 5: [6, 7, 8, 9]. From this table we Count the The 1 indicates true, while the x(number) indicates multiples needed. different ways in which each sum may be made. 92 - 94, Section 3. 8+ 5 = 8 + 2 + 3 = 10 + 3 = 13 ).

That way we can avoid printing permutations. And finally we have to get to 2-2 = 0 before index 5. This agrees with stars and bars since $\binom{10+2}2=66$. 190 The test cases are generated such that the number of unique combinations that sum up to target is less than 150 combinations for the given input. @DinhQuangTuan I added an explanation. sum. 361 Thanks for your response, but the spread sheet uses all numbers required to get the sum. ) 8! The original problem is just a particular case of this one, where we have as many occurrences of each coin as needed to make the total amount with each single coin value.
