remove-duplicates-from-sorted-list (删除),题意略:思路:先造一个点它与所有点的值都不同,那么只要后面两个点的值相同就开始判断后面是不是也相同,最后将相同的拆下来就可以了。
Python'sdictclass has afromkeysclass methodwhich accepts aniterableand 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 (as of ...
List<Integer> myList = List.of(0, 1, 1, 2, 3, 5, 6, 0, 0, 1);System.out.println(myList.size());//prints 10 When we call the distinct method of the Java Stream API, this removes duplicates from the returned list. When we print out the list’s size a second time the outp...
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 def my_function(x): return list(dict.fromkeys(x))mylist = my_function(["a", "b", "a", "c", "c"]...
This post will discuss how to remove duplicates from a list in C# without destroying the original order of the elements. 1. UsingHashSet We know thatHashSet<T>does not permit any duplicate elements. Therefore, if we convert the given list (with duplicates) toHashSet<T>and then convert it...
