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,

Write a function little_sum (number_list, limit) that returns the sum of only the numbers in number_list that are less than or equal to the given limit. In this question you must use a for loop and you are not allowed to use the sum function. For example: Test Result numbers = [1, 2, 3, 4, 5, 6] total = little_sum(numbers, 3) print(total) values = [6, 3, 4, 1, 5, 2] 10 total = little_sum(values, 4) print(total)
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",
Define a function named display_word (encrypted_list) which takes a list of characters as a parameter. The function prints the parameter list as shown in the examples below. Note: you can assume that the parameter list is not empty. For example: Test Result **¹, ¹*¹'] GUESS THE WORD: h**** data = ['h', '*', '*', display_word (data) ''*', '*', '*'] GUESS THE WORD: s****** data = ['s', '*', display_word (data)
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):
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. 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

In c++, please! Thank you! Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is: 20 10 30 40 -1 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 The following code is given: #include <iostream> using namespace std; // TODO: Write a void function SelectionSortDescendTrace() that takes// an integer array and the number of elements in the array as arguments,// and sorts the array into descending order.void SelectionSortDescendTrace(int numbers [], int numElements) { } int main() { int input, i = 0; int numElements = 0; int numbers [10]; // TODO: Read in a list of up to 10 positive…
