Example of Output: Input a string:..... 2. Demonstrate by writing a program to calculate the frequency of every letter in an input string s. a. Your program should be able to input a string. b. Your message should be constructed from at least 50 letters. c. Calculate the frequency of each element in the string and store the results into a linked list. d. Your program should be able to print each letter and its respective frequency. e. Identify the letter with the highest frequency in your message. f. Sort the linked list in ascending order using an algorithm of your choice. Write a short justification of your choice. letters r C frequency 1 4 6 12 20 24 30

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. Input values should be added to the list until -1 is entered. Ex: If the input is: 30 50 10 70 65 -1 the output is: 20 40 60 55

please solve this question and the result output should EXACTLY  match as given

Given a string with duplicate characters in it. Write a program to generate a list that only contains the duplicate characters. In other words, your new list should contain the characters which appear more than once. Suggested Approach Used two nested for loops. The first for loop iterates from 0 to range(len(input_str)). The second for loop iterates from first_loop_index + 1 to range(len(input_str)). The reason you want to start at first_loop_index + 1 in the nested inner loop is that the outer loop already checks the current character. In the nested inner loop, you want to check the remaining characters in the input string. If the current character of the outer loop matches the character of the nested loop AND the character is not already IN the duplicate list, append it to the list nhantran Sample Output 1 List of duplicate chars: ['n', 'a'] Sample Input 2 pneumonoultramicroscopicsilicovolcanoconiosis Sample Output 2 List of duplicate chars: ['p', 'n', 'u', 'm', 'o', 'l', 'r', 'a',…

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…

Objective: Write syntactically correct while/for loops Given a list of numbers and a number n, return the sum of the first n elements in the list. Assume n is less than or equal to the length of the list. For example, given [1, 1, 1, 5] and n=3, the function should return 3. (i.e. 1+1+1) user_code.py 1 # starter code 2 def sum_to_n(numbers, n): 3 4 & in 5 # your code here (replace pass with your code) *
