Chapter 9, Problem 8TF
Explanation of Solution
Sets:
- • A python set is used to create an unordered collection of unique objects.
- • The built in “set()” function is used in python to create the sets.
- • The “set()” function can take the arguments to initialize the set.
- • If multiple copies of values are passed in the argument list, only one copy will be stored in the list.
- • The set can contain different types of data at the same time so the ordering of different types of data does not make sense.
Syntax:
In python, a set is created as follows:
setName = set(elementList)
In the above syntax,
- • The “setName” specifies the name of the set variable...

populateSelectMenu function
The function populateSelectMenu should exist.
The function populateSelectMenu should return undefined if it does not receive users data.
The function populateSelectMenu selects and returns the select menu.
The function populateSelectMenu receives the option elements from createSelectOptions and appends them to the select element.
C++
You should create a loop which will ask user if they want to insert, delete, display and exit. Then call the corresponding method based on the user's input. The loop will only stop once user entered "Exit"
Topic: LinkedList
State True/False: A set may contain a specific value more than once, however, only unique value will be stored.

The next number in the sequence is obtained by using this formula: a_n=a_1*r(n-1) While the sum of all numbers in the sequence is obtained using any of these formulae: If r= 1, sum=a*n Ifr != 1 and r> 1, sum = a[(rª-1)/(r - 1)] Ifr != 1 and r < 1, sum = a[(1-r)/(1-r)] where a_n = next number in the sequence, a_1 = first number in the sequence, r = common ratio, n = number of terms Your task is to write a Python program that 1: Accepts the necessary inputs from the user, i.e., start value (a_1), common ratio (r), and number of generate to generate (n). 2.

- ____ is the process of examining the elements of an array in order, looking for a match for a specific value.arrow_forwardCENGAGE MINDTAP Programming Exercise 9-2A | Instructions The mean of a list of numbers is its arithmetic average. The median of a list is its middle value when the values are placed in order. For example, if an ordered list contains 1, 2, 3, 4, 5, 6, 10, 11, and 12, then the mean is 6, and their median is 5. Write an application that allows you to enter nine integers and displays the values, their mean, and their median. An example of the program is shown below: Enter number 6 12 Enter number 7 14 Enter number 8 16 Enter number 9 18 You entered: 2, 4, 6, 8, 10, 12, 14, The mean is 10.0 and the median is 10 YE ا... | 16, 18 MeanMedian.java 1 +arrow_forwardMusic Player – Songs in music player are linked to previous and next song.

- Problem Charge Account Validation Create an application that reads the contents of the file into an array or a List . The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List , the program should display a message indicating the number is valid. If the number is not in the array or List , the program should display a message indicating the number is invalid.

In this formula, positions start from 1, not 0, and we use the letter i to denote the position since we will be using the letter n for something else. For example, the sequence of "octagonal numbers" that springs forth from s = 8 starts with 1, 8, 21, 40, 65, 96, 133, 176... Given the number of sides s and an arbitrary integer n, this function should return the s-gonal integer closest to n. If n falls exactly halfway between two s-gonal numbers, return the smaller one. n s Expected result 5 3 6 27 4 25 450 9 474 10**10 42 9999861561 10**100 91 10000000000000000000000000000000000000000000000000416332753518329478897755794704334003003544212420356arrow_forward
