Taking out the trash may require 3 steps (tying up a garbage bag, bringing it outside & dropping it into a dumpster). Of course I am aware that the complexity could change from implementation to implementation, but I am interested only in the standard implementation. Complexity is a factor involved in a complex process. Each conditional statement has time complexity = O(1). Complexity Analysis for finding the duplicate element Space Complexity: O(n), we are using a extra memory in the for of hash which which will have a size of n in the worst case. Time complexity: O(n^2) where n is the length of the input string.
