Assignment 5A: Multiple Frequencies. In the last assignment, we calculated the frequency of a coin flip. This required us to have two separate variables, which we used to record the number of heads and tails. Now that we know about arrays, we can track the frequency of all numbers in a randomly generated sequence. For this program, you will ask the user to provide a range of values (from 1 to that number, inclusive) and how long of a number sequence you want to generate using that number range. You will then generate and save the sequence in an array. After that, you will count the number of times each number occurs in the sequence, and print the frequency of each number. Hints: You can use multiple arrays for this assignment. One array should hold the number sequence, and another could keep track of the frequencies of each number. Sample Output #1: What's the highest number you want to generate?: 5 How Long of a number sequence do you want to generate?: 10 Okay, we'll generate 10…

In c++ langauge Household Expense - Create arrays (size 15) that will hold the following information: category and amount). Allow the user to enter the category (ex.Water bill) and the corresponding amount spent on it. After the data entry, display the household categories and its corresponding amount in desceding order (highest amount first) and the total amount spent in a month. This is a sample output below

Topics: User-defined functions, list, string, docstringProblem Statement: This program finds the unique letters from a given string and printsthe unique letters and their count. For example: word ‘LITTLE’ has ‘L’, ‘I’, ‘T’, ‘E’ are theunique letters.Lab Scenario:The program repeats until hits ‘n’. The program takes a user input of a string. The programfinds the unique letters in the string, add them in a list and displays the list and their count.Consider the following important points:1) You need to design a user-defined function named count_unique_letters whichtakes user word as parameter and returns the list of unique letters calledunique_letters in the given word.a. Hint: Iterate over each letter in user word, check if the letter is in the list, if notadd it to the list, otherwise continue to the next letter. A ‘in’ keyword can helpto determine if a character in the unique_letters list.b. You need to write a simple docstring for this function.2) Your program must have a main()…
