@kc021 's instructions: Not sure how easy or hard this will be, but... Welcome to the ninth codegolf challenge! In this challenge, run a setwise XOR through two lists, and output the results in an output list. A setwise XOR means that you will only include items that are in exactly ONE list, but NOT both lists. So [1, 4, 5, 6] and [5, 2, 1] as input1 and input2, respectively, would result in an output of [4, 2, 6] or any of its permutations.
Looked at @AmazingMech2418 's for spoilers. Seems so obvious now lol. Shortened it by 2 blocks with an insert instead of an if statement. Fairly sure this is optimal
