Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array nums = [1,1,2], Your function should re...

What if duplicates are allowed at most twice? For example, Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, 2 and 3. It doesn't matter what you leave beyond the new length. ...
If you like to have a function where you can send your lists, and get them back without duplicates, you can create a function and insert the code from the example above. Example defmy_function(x): returnlist(dict.fromkeys(x)) mylist =my_function(["a","b","a","c","c"]) ...
Python's dict class has a fromkeys class method which accepts an iterable and makes a new dictionary where the keys are the items from the given iterable.Since dictionaries can't have duplicate keys, this also de-duplicates the given items! Dictionaries also maintain the order of their items ...
Last but not least, we are traversing the set, which, in the worst scenario, will take O(N) time (if every element is unique) As a result, this method’s worst-case time complexity to remove duplicates from an array is O(N)+O(NlogN)+O(N)=O(NlogN). Auxiliary Space Analysis For...
Do not allocate extra space for another array, you must do this bymodifying the input array in-placewith O(1) extra memory. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 示例1:
To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
