I need help Note: It`s a python Implement the following:1) Code a dictionary from the following data (the key is the name and the value is the age): Ann 53 Bill 24 Calvin 36 David 252) Use a loop to print all ages on the same line.3) In the loop above, calculate the average age with a precision of two decimal places. 4) Print the average. Do not just print(34.5). Just make sure to precisely match the output format below.Write your code in the ANSWER area provided below (must include comments if using code is not covered in the course).Example Output53 24 36 25Average: 34.50

The top three most popular male names of 2017 are Oliver, Declan, and Henry, according to babynames.com. Write a program that modifies the male_names set by removing a name and adding a different name. Sample output with inputs: 'Oliver' 'Atlas' { 'Atlas', 'Declan', 'Henry' } NOTE: Because sets are unordered, the order in which the names in male_names appear may differ from above. Code writing challenge activity demo 461710.3116374.qx3zqy7 1 male_names 2 name_to_remove = input() 3 name_to_add=input() 4 = 11 { 'Oliver', 'Declan', 'Henry' } 5 6 7 print (male_names) Your solution goes here '''
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…
Using c++ Contact list: Binary Search A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…
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):

Test it from t01.py. Hint: you may use find_indexes in the function to solve the problem. The function does not ask for input and does no printing - that is done by your test program.
