Given the following function header: def second_largest(1st: list[int]) -> int: Given a list of integers, return the second largest item in the 1 ist without modifying <1st>. Precondition: len(1st) >= 2 and given the following list of test cases (labelled TEST 1 through TEST 6): TEST 1: second_largest([2, 1]) TEST 2: second_largest([3, 0]) TEST 3: second_largest([3, 1, 2]) TEST 4: second_largest([3, 1, 4]) TEST 5: second_largest([3, 1, ®]) TEST 6: second_largest([3, 1, -1]) Identify any tests which duplicate cases tested earlier in the list. For example, if TEST 3 duplicates something TEST 1 or TEST 2 have done, then select TEST 3 (as it has a duplicate test case). O TEST 1 O TEST 2 O TEST 3 O TEST 4 O TEST 5 O TEST 6

Given the following function header: def longest_chain(lst: list[int]) -> int: II II II Given a list of integers, return the length of the longest chain of 1's that start from the beginning. Precondition: 1st is non-empty II II II which one of the cases below is the least useful to check? Select the best answer. o longest_chain([0]) o longest_chain([1, 1, O]) o longest_chain([1, 1, 0, 1]) o longest_chain([1, 0, 1, 1]) o longest_chain(['1', '1', 'O', '1', '1', '1'])
Write a function that takes a list and returns a new list thatcontains all the elements of the first list minus all the duplicates.• You must use loop in your defined function. Using the build-in function set ()will be graded zero.• Please submit your code and console screenshots to bartleby. Code contain-ing syntax error will be graded zero.• Example: The function takes a list 1,2,3, 4, 3, 2, 1 and outputs 1, 2, 3, 4.
The two-dimensional lists m1 and m2 are identical if they have the same contents. Write a function that returns True if m1 and m2 are identical, usingthe following header:def equals(m1, m2): Write a test program that prompts the user to enter two lists of integers and displays whether the two are identical.
Write a function called find_duplicates which accepts one list as a parameter. This function needs to sort through the list passed to it and find values that are duplicated in the list. The duplicated values should be compiled into another list which the function will return. No matter how many times a word is duplicated, it should only be added once to the duplicates list. NB: Only write the function. Do not call it. For example: Test Result random_words = ("remember","snakes","nappy","rough","dusty","judicious","brainy","shop","light","straw","quickest", "adventurous","yielding","grandiose","replace","fat","wipe","happy","brainy","shop","light","straw", "quickest","adventurous","yielding","grandiose","motion","gaudy","precede","medical","park","flowers", "noiseless","blade","hanging","whistle","event","slip") print(find_duplicates(sorted(random_words))) ['adventurous', 'brainy', 'grandiose', 'light', 'quickest', 'shop', 'straw', 'yielding']…

Consider the following function access_element_by_index that returns the iterator to the element at the index i in the list l. typedef std::list<int> int_list; int_list::iterator access_element_by_index(size_t I, int_list &) { assert( ? ); … } Assume the first element of the list is at the index 0, the second at the index 1, and so on. If the function is required to return an iterator that can be dereferenced, determine the precondition of the function, and write an assertion to validate it. (You don’t need to implement the functions).
3. Write the remove_evens() function that receives a list of integers as a parameter and returns a new list of integers containing only the odd numbers from the original list. Ex1) If n = [1, 2, 3, 4, 5, 6], remove_evens(n) returns [1, 3, 5]. Ex2) If n = [2, 4, 8], remov move_evens(n) returns [].
In OCaml Programming Language, write a function: val prime_separator : int list -> int list * int list = <fun> that takes an integer list as an input, and returns a pair of integer lists where the prime numbers are in the first while the composite numbers are in the second returned list. #prime_separator [1; 2; 3; 4; 5; 6; 7; 8; 9; 10; 11];; - : int list * int list = ([11; 7; 5; 3; 2], [10; 9; 8; 6; 4; 1])
python wirte a function max_indexes(xs) that inserts a list xs with numbers and returns a list of indexpositions where the list has local maximum values. A local maximum value is a number in the list that has a smaller number before and after. for example in this list has a local maximum at position 2 and 7: [3, 4, 5, 2, 1, 0, 4, 6, 4, 2, 1] Here the function should return [2, 7]
Pascal triangle! write a function(in OCaml) val nextpascalrow : int list -> int list = that given a list of integers that correspond to a row of the pascal triangle, it calculates the next row of the pascal triangle. # nextpascalrow [1; 6; 15; 20; 15; 6; 1];; - : int list = [1; 7; 21; 35; 35; 21; 7; 1]
Given the following function header: def second_largest(1st: list[int]) -> int: Given a list of integers, return the second largest item in the list without modifying . Precondition: len(1st) >= 2 and given the following list of test cases (labelled TEST 1 through TEST 6): TEST 1: second_largest ([1, 2]) TEST 2: second_largest([e, 3]) TEST 3: second_largest([2, 1])| TEST 4: second_largest ([1, 3, 0]) TEST 5: second_largest([1, 3, 2]) TEST 6: second_largest([3, 1, 0])] Identify any tests which duplicate cases tested earlier in the list. For example, if TEST 3 duplicates something TEST 1 or TEST 2 have done, then select TEST 3 (as it has a duplicate test case). O TEST 1 O TEST 2 O TEST 3 O TEST 4 O TEST 5 O TEST 6
