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 .
