Python Please Implement a function dedup(lst: list) -> list: that returns a de-duplicated version of the input list. Elements appear in the same order as the input list, but subsequences of equal elements are replaced by one representative. For example, dedup([]) = [], dedup([1, 1, 2, 1, 1]) = [1, 2, 1].

- Write a function split n l that splits the list l and returns a pairof lists containing the first n elements of l and the rest of l, wheresplit has the type int -> ’a list -> (’a list * ’a list). For ex-ample, split 3 [1,2,3,4,5] returns the pair ([1,2,3], [4,5]) andsplit 3 [1,2,3] returns ([1,2,3], []).write a Python function that takes in a list of integers (nums) and finds whether the list consists of any duplicate numbers, the function returns True or False accordingly (Note: this is not a linked list, just a Python list). Function must run in place and cannot use Python’s built-in Set() structure. Make sure to provide the most efficient algorithm in terms of its time and space complexity.Python Implement a singly linked list with the following functions: - add_head(e) - add_tail(e) - find_3rd_to_last() - returns element located at third-to-last in the list - reverse() - reveres the linked list, note, this is not just printing elements in reverse order, this is actually reversing the list
- Write a program REMOVE_DUPLICATES that will remove duplicateelements in a list L that occur consecutively. The program should return the list withits elements in the same order of their appearance in the original list, but with theconsecutive duplicate elements removed.For example, for a list with elements {A, B, C, C, C, C, D, D, E, F, F}, theoutput list produced by REMOVE_DUPLICATES should be {A, B, C, D, E, F}.Write a function that takes a list removal(L), delete from it all the elements whose indicesare divisible by 3. And return the resulting list after removing unwanted elements.Example:>>>removal(['A', 'B', 'C', 'D', 'E'])['B', 'C','E'List of triples or a triple of lists? Write a function l3_of_3l : ’a list * ’b list * ’c list -> (’a * ’b * ’c) list = that transforms a triple of lists into lists of triples. If lengths don’t match then ignore leftover elements. examples l3_of_3l ([1;2;3],[1.;2.],[’a’;’b’;’c’;’d’]);; - : (int * float * char) list = [(1, 1., ’a’); (2, 2., ’b’)] l3_of_3l ([1.;2.],[’a’;’b’;’c’;’d’],[1;2;3]);; - : (float * char * int) list = [(1., ’a’, 1); (2., ’b’, 2)]
- Write a Python Code for the given function and conditions: Given function: def insert(self, newElement) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.Write a function with the signature below that returns the sum of the last k elements of a singly linked list that contains integers. int returnSumOfLastKNodes(Node* head, int k) Example: 10 -> 5->8->15->11->9->23 10 represents the head node, returnSumOfLastKNodes(Node* head, 4) will return 58.Write a program that inserts the following numbers into two (2) empty doubly linked list.L1 50 30 25 75 82 28 77L2 50 40 25 75 80 21 37 30Hint: Put the median at the first element of linked list for both linked list and after insertingmedian element at the first node, do not pass that element again. Median Formula: (n+1)/2a) Implement an insert function for both L1 and L2.b) Implement a function to delete 80 from L2.c) Implement a function to check L1 and L2 are really the same list of nodes or not.Note: You are not allowed to use any built-in Data Structure classes to implement abovescenario.
- Implement a function countMultiples in Python that: accepts a single argument, a 2-dimensional list (e.g, list of lists) containing non-negative integers, and returns the count of those integers that are multiples of 5 but that are not not multiples of 10. (e.g., 65 should be counted, but 80 should not be counted) sample usage: >>> countMultiples( [[1,2,3],[4,5],[6,7,8,9]] ) # 5 counts1Write a Python function `removeDuplicates(myList)` that removes duplicate values from a list. While the algorithm for this problem might seem trivial, its implementation is not. In general, it is not advisable to modify a list while you are iterating on it, as in the following pseudo-code: for element in myList: if <condition>: <remove element(s) from myList> # recipe for disasterIn python, remove_from_list(my_list, indices): Takes two lists as input. Creates a new list from the first input list by removing the elements at indices given by the integers in the second input list, then return the new list. The indices in the second input list may have any order. For example, if the first input list is [4, 8, 12, 16], and the second input list is [0, 2], then the new list returned from the function should have the 4 and the 12 removed, because they were at indices 0 and 2 of the original list. Note: You do not need to consider negative indices for this function. >>> remove_from_list(['abc', 'def', 'ghi'], [1]) ['abc', 'ghi'] >>> strs = ['The', 'quick', 'brown', 'fox'] >>> remove_from_list(strs, [0, 3]) ['quick', 'brown'] >>> strs ['The', 'quick', 'brown', 'fox'] # original list is unchanged >>> remove_from_list(['The', 'quick', 'brown', 'fox'], [3, 0]) ['quick', 'brown']
