Given the following function header: def longest_chain(lst: list[int]) -> int: 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 which one of the cases below is the least useful to check? Select the best answer.

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']…

1.Given the argument passed to the function is a list containing integer values, what does the function return   def mystery1(someListOfValues: list):total = 0for value in someListOfValues:total += valuereturn total/len(someListOfValues)   2. The function below is to find the largest value in a list passed by parameter. Does it work as intened (yes or no)? If not give an example of an argument it would not work for.   def maxValue(someListOfValues:list):"""returns the largest value the list passed by parameter"""value = 0for num in someListOfValues:if num > value:value = numreturn value     3.Write a function called loadNames()  that will open a file called names.txt and build a list of its contents and return it.     Function Call: names = loadNames()print(names)   Sample ouput:  ['Nolan Rafaj\n', 'Brandon Brzuszkiewicz\n', 'Amanda Vozari\n', 'Chase Harper\n', 'Bryce Conner']

PYTHON Complete the function below, which takes two arguments: data: a list of tweets search_words: a list of search phrases The function should, for each tweet in data, check whether that tweet uses any of the words in the list search_words. If it does, we keep the tweet. If it does not, we ignore the tweet. data = ['ZOOM earnings for Q1 are up 5%', 'Subscriptions at ZOOM have risen to all-time highs, boosting sales', "Got a new Mazda, ZOOM ZOOM Y'ALL!", 'I hate getting up at 8am FOR A STUPID ZOOM MEETING', 'ZOOM execs hint at a decline in earnings following a capital expansion program'] Hint: Consider the example_function below. It takes a list of numbers in numbers and keeps only those that appear in search_numbers. def example_function(numbers, search_numbers): keep = [] for number in numbers: if number in search_numbers(): keep.append(number) return keep   def search_words(data, search_words):
