That works for all subsequent values of M. Power set is a type of sets, whose cardinality depends on the number of subsets formed for a given set. The solution set must not contain duplicate subsets. The second recursive call causes another [1,2] to be appended twice because when recursion unravels after [1,2,3], it will go into the second recursive call with subset = [1,2] and nums being the the empty list, so [1,2] gets appended twice. Given an integer array nums that may contain duplicates, return all possible subsets (the power set). Definition-Power Set. December 3, 2024. 90.
