WebJun 23, 2014 · To reiterate : A subset if formed by including some or all of the elements of the original set. Thus, to create a subset, you go to each element, and then decide whether to keep it or drop it. This means that for each element, you have 2 decisions. Thus, for a set, you can end up with 2^N different decisions, corresponding to 2^N different subsets. WebOct 6, 2024 · Otherwise, add the current array element to the current subsequence and traverse the remaining elements to generate subsequences.
