Generate subsets of string using recursion

WebFeb 20, 2024 · Time Complexity: O(2^n), where n is the length of the string. Space Complexity: O(2^n), as the recursive stack grows until the length of the string. Alternate Solution: One by one fix characters and recursively generate all subsets starting from them. WebMar 8, 2024 · Time Complexity: O(n * 2 n), where n is the size of the given string Auxiliary Space: O(n), due to recursive call stack. Method 4: Using Binary representation of numbers to create Subsequences. String = “abc” All combinations of abc can be represented by all binary representation from 0 to (2^n – 1) where n is the size of the string .

WebSubsets - Given an integer array nums of unique elements, return all possible subsets (the power set). The solution set must not contain duplicate subsets. Return the solution in any order. WebApr 6, 2015 · The number of subsets of a set with n elements is 2 n.If we have, for example, the string "abc", we will have 2 n = 2 3 = 8 subsets.. The number of states that can be represented by n bits is also 2 n.We can show there is a correspondence between enumerating all possible states for n bits and all possible subsets for a set with n elements:

WebMar 19, 2013 · The recursion ends when the string is empty (because it never enters the loop). If your really want no loops, you will have to convert that loop to another recursion. Now we want to generate ab, ac and cb from abc. powerset (string) { add string to set; add powerset2 (string,0) to set; return set } powerset2 (string,pos) { if pos WebThe time complexity of the above solution is O(n.2 n), where n is the size of the given set.. Approach 2. For a given set S, the power set can be found by generating all binary numbers between 0 and 2 n-1, where n is the size of the set.

WebNov 2, 2012 · Instead of recursing on the letters of the word, you could recurse on the word length. For example, on the top level of recursion you could find all substrings with word.length() letters then word.length() - 1 letters and so on. This would probably require two recursive methods though, one to loop through the word lengths and one to loop …
