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...
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 ...
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"]) ...

Starting from Python 3.7, we can use a regular dictionary to remove duplicates from a list, as they are guaranteed to be ordered. The idea is to use the items of the original list as keys of the dictionary, and assign any value to them (such asTrueorNone). Then we can get the keys...
