f second_largest(lst: List[int]) -> int: Given a list of integers, return the second largest item in the li without modifying . You cannot use any of python's builtin sorting functions. Do not attempt to sort the list yourself either. As a sanity check, you can ensure that your function returns what "return sorted(lst)[-2]" would. (DO NOT COPY THIS) For example, an input [1, 2, 3] should return an output of 2, since 2 is the second largest integer in the list. Note that when we say second largest, we do not mean second largest distinct element. That means that [1, 2, 4, 4] should return 4, not 2. Precondition: the input list has at least 2 elements.

This should be in Python, Thank you!!
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 10

The function sum_evens in python takes a list of integers and returns the sum of all the even integers in the list. For example: Test Result print(sum_evens([1, 5, 2, 5, 3, 5, 4])) 6 print(sum_evens([5, 5, -5, -5])) 0 print(sum_evens([16, 24, 30])) 70
The function should be written in python language. Write a function called "zero_triples" to return all triples in a list of integers that sum to zero. You can assume the list won't contain any duplicates, and a triple should not use the same number more than once. [In]: zero_triples([1, 2, 4]) [Out]: [] [In]: zero_triples([-3, 1, 4, 2]) [Out]: [[1, 2, -3]] [In]: zero_triples([-9, 1, -3, 2, 4, 5, -4, -1]) [Out]: [[-9, 4, 5], [1, -3, 2], [-3, 4, -1], [5, -4, -1]]
Q3
Python’s list method sort includes the keyword argument reverse, whose defaultvalue is False. The programmer can override this value to sort a list in descendingorder. Modify the selectionSort function so that it allowsthe programmer to supply this additional argument to redirect the sort. selectionSort function: def selectionSort(lyst, profiler):i = 0 while i < len(lyst) - 1:minIndex = ij = i + 1 while j < len(lyst):profiler.comparison() # Countif lyst[j] < lyst[minIndex]:minIndex = jj += 1 if minIndex != i:swap(lyst, minIndex, i, profiler)i += 1 def swap(lyst, i, j, profiler):"""Exchanges the elements at positions i and j."""profiler.exchange() # Counttemp = lyst[i]lyst[i] = lyst[j]lyst[j] = temp Use this template in Python to modify the function above: def selection_sort(input_list, reverse):sorted_list = []#TODO: Your work here# Return sorted_listreturn sorted_listif __name__ == "__main__":my_list = [1, 2, 3, 4, 5]print(selection_sort(my_list, True)) # Correct Output: [5,…

PYTHON:Please help me fix my code. It was supposed to ask the user to input an inorder traversal and let them choose whether to enter postorder or preorder, then identify the order of the missing traversal, just like the image below. However, my code can only identify the missing traversal, but not its order. Please help me fix it.
