5. A couple of improvements you can make to your algorithm: 1) Use sets instead of a list for your solution. Using a set will insure that you don't have any duplicate and you don't have to do a if new_solution not in solutions: check. 2) Add an edge case check for an all zero list. Not too much overhead but saves a HUGE amount of time for …Nov 26, 2017 · a + b + c = 0. Solution is to just convert this into two pointer technique of solving 2SUM problem.
