Time complexity is to create a dictionary out of the elements in the list to remove all duplicates and convert the dictionary back to a list. #, ] Method 2: Temporary Dictionary ConversionĪlgorithm: A more efficient way in terms of ![]() The problem is that this method has quadratic time complexity because you need to check for each element if it exists in the list (which is n * O(n) for n elements). How to remove all duplicates of a given value in the list?Īlgorithm: Go over each element and check whether this element already exists in In this article, I’ll show you how (and why) it works-so keep reading! What’s the best way to remove duplicates from a Python list of lists? This is a popularĬoding interview question at Google, Facebook, and Amazon. ![]()
