Write a function named "freq(1) that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency. For example, "freq([1,2,3,4,5,2,3,4,5,3,4,5,4,5,4]) returns (4,5) because number 4 appears 5 times in this list. If multiple numbers appear as most frequent, then the first element of the returned tuple is a list of all those numbers. For example, freq([1,2,3,1,2,1,2,3,1,2]) will return ([1,2], 4) because both 1 and 2 appear 4 times in the list. def freq(1): # remove the following line to solve this question return

Define a function named check_game_finished (encrypted_list) which takes a list of characters as a parameter. The function returns True if the game is over, and False otherwise. The game is over when there is no longer any "*" characters in the parameter list. For example: Test Result False True data = ['h', '*', ¹*¹, ¹*¹, ¹*'] print(check_game_finished (data)) data = ['h', 'e', '1', '1', 'o'] print(check_game_finished(data)) data = ['s', ¹*¹ 'd'] False print(check_game_finished (data))
Create a function that returns the characters from a list or string ron odd or even positions, depending on the specifiers. The specifier will be "odd" for items on odd positions (1, 3, 5, ...) and "even" for items on even positions (2, 4, 6, ...). Examples char_at_pos([2, 4, 6, 8, 10], "even") [4, 8] # 4 & 8 occupy the 2nd & 4th positions - char_at_pos ("EDABIT", "odd") "EAI" # "E", "A" and "I" occupy the 1st, 3rd and 5th positions char_at_pos(["A", "R", "B", "I", "T", "R", "A", "R", "I", "L",
have been given a singly linked list of integers. Write a function that returns the index/position of integer data denoted by 'N' (if it exists). Return -1 otherwise. Note :Assume that the Indexing for the singly linked list always starts from 0.Input format :The first line contains an Integer 'T' which denotes the number of test cases. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line contains the integer value 'N'. It denotes the data to be searched in the given singly linked list. Remember/Consider :While specifying the list elements for input, -1 indicates the end of the singly linked list and hence -1 would never be a list element. Output format :For each test case, return the index/position of 'N' in the singly linked list. Return -1, otherwise. Output for every test case will be printed in a separate line. Note:You do not need to print anything; it has already been taken care of. Just implement…
Question 2: Write a function that takes a string as its only argument and returns a sorted list of characters used in the string. The resulting list should only contain lower case letters and each letter should exist only once. Also, the resulting list shouldn't contain any spaces or punctuation marks, such as ",;.!?". For example, strletters ("We are, the Champions!") returns ['a', 'c', 'e', 'h', 'i', 'm', 'n', 'o', 'p', 'r', 's', 't', 'w'] def strletters(istr):
PLZ write in SML language. Thank you Write a function maxGroup that determines, for a given integer list, the stored number of the longest consecutive group of equal numbers. For example, maxGroup [2, 9, 8, 8, 8, 7, 9, 1] should return 8 since there are three consecutive 8s in the list. Hint: Solve the problem in two steps. First, determine the length of each group of equal numbers. Then, determine which is the largest.
In program problem5.py, write a function named sums that takes 3 arguments: 2 lists of integers nums1 and nums 2, and an integer target; then return a tuple containing indices i and j of the two numbers in nums 1 and nums 2, respectively, where the numbers at that indices add up to target (i.e, nums1 [i] + num2[j] = target). If there is no solution, return "Not found". The function sums must contain exactly only one loop (either a for-loop or a while-loop), otherwise you will get no point. A nested-loop is considered as more than one loop. You can assume that each given input either have exactly one solution or none. Below is the code of the main function in problem5.py, complete the program by writing the function sums. Note that the values of nums 1, nums2 and target are given in the main function which can be changed in the code. This program does not take any input. if name __main__': nums1 = [11, 2, 15, 7, 8] nums2 = [3, 4, 5] target = 9 print(sums(nums 1, nums2, target)) Example…
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']…

Write a function named 'freq(I) that takes a list 'I' of numbers and returns a tuple of the most frequent number and its frequency.

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.

I am very confused on how to answer this and any thing will help. Create a function that accepts a single list. Inside the function, have nested for loops (a for loop inside a for loop). The outer for loop iterates through every item in the list. The inner loop iterates through every subitem in item, and prints it. Test the function by passing it the list [ [0, 1, 2], [3, 4, 5], [6, 7, 8] ].
Making a list of numbers from 2 to n Create a function named make-2-n-list that takes in one parameter, the end number. It should return a list of numbers from 2 to that number.(make-2-n-list 30) ➔(2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 1718 19 20 21 22 23 24 25 26 27 28 29 30) Hint: make a function that makes the list backwards (easy right-fold pattern), then look at your recursive case and think backwards. Pls use scheme(R5RS) to finish this program!Thank you a lot!
