Write a function extrait_pairs that takes as an argument a list l1 and returns the list obtained from l1 keeping only the even integers (and without changing their order). Be careful, l1 must not be modified by the function.
Example: extrait_pairs([4, 7, 12, 0, 3]) is [4, 12, 0] and extrait_pairs([21, 17, 3]) is [ ].

- Please answer it in Python Write a function min_pair that takes a list as an argument and returns the smallest even integer contained in the list. If the list contains no even integers, the function will return None. Example: min_pairs([4, 7, 12, 0, 21, 5]) is 0 min_pairs([9, 3, 1]) is None. min_pair([16, 13, 10, 102, 7, 23]) is 10Please answer it in Python Write a function insere_milieu that takes as an argument a list l and an element elem and returns the list obtained from l by adding elem "in the middle" of l, that is: If the length of l is even, the item is added once, in the middle of the list. If the length of l is odd: the element is added on either side of the central element. Example: insere_milieu([4, 7, 12, 3], 0) is [4, 7, 0, 12,3] insere_milieu([9, 3, 5, 6, 2], 1) is [9, 3, 1, 5, 1, 6, 2].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.
- 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 in python with a function isPal(L), where L is a list of integers, and the function returns True if the list is a palindrome, False otherwise. For example [5, 2, 9, 9, 2 5] is a palindrome. Use the reverse() method of list and check if the reversed list is the same as the original list.Write a function Delete(x,L) in Pascal that deletes last occurrence of x in a singly linked list and returns the number of elements (not the elements*) before the deleted element x. MANDATORY FOR CODE TO BE IN PASCAL.
- Write a python function named replaceVal(list, valToBeReplaced, newValue) which takesthe above described inputs and finds the value ‘valToBeReplaced’ in the list. If it ispresent, it is replaced with newValue and the updated list is returned, otherwise thesame list is returned.Example:[1,2,3,4,5], 5, 20Output: [1,2,3,4,20] Example:[10, 15, 20, 25, 30], 5, 20Output: [10, 15, 20, 25, 30]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'Python Write a function revers_all (sequence) that takes an arbitrary nested list sequence with arbitrary elements and returns a new list that has the same nested structure, but where all lists both at the top level and at all nested levels are reserved ("backwards") examplereverse_all ([1, 2, 3, [4, 5, ['x', 7]], 8]) becomes[8, [[7, 'x'], 5, 4], 3, 2, 1] I sent parameters can not be changed. It is thus a completely new list to be returned.It is allowed to solve the task recursively or itrelatively or with a compilation of these methods. Your function may not make any readings or printouts Use this program to test import copy sequence = eval(input()) seq_copy = copy.deepcopy(sequence) result = reverse_all(sequence) print (result) if results is sequence: print("Your function does not create a new list") if sequence != seq_copy: print("Your function changes in that submission list")
- 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.In 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']Suppose a node of a linked list is defined as follows in your program: typedef struct{ int data; struct Node* link; } Node; Write the definition of a function, printOdd(), which displays all the odd numbers of a linked list. What will be the time complexity of printOdd()? Express the time complexity in terms of Big-O notation.
