COMPUTER SCIENCE Create a class called StatSet that can be used to do simple statistical calculations. The methods for the class are: _ _init_ _(self) Creates a statSet with no data in it. addNumber(self, x) x is a number. Adds the value x to the statSet. mean(self) Return the mean of the numbersin this StatSet. median(self) Returns the median of the numbers in this statSet. stdDev(self) Returns the standard deviation of the numbers in this statSet. count(self) Returns the count of numbers in this statSet. min(self) Returns the smallest value in this statSet. max(self) Returns the largest value in this statSet. Test your class with a program similar to the simple statistics program. Verified answer COMPUTER SCIENCE Write a pseudocode algorithm for the inorder traversal. Verified answer
COMPUTER SCIENCE Write a program that uses a structure to store the following data about a customer account: Name Address City, State, and ZIP Telephone Number Account Balance Date of Last Payment The program should use an array of at least 10 structures. It should let the user enter data into the array, change the contents of any element, and display all the data stored in the array. The program should have a menu-driven user interface.

COMPUTER SCIENCE A Caesar cipher is a simple substitution cipher based on the idea of shifting each letter of the plaintext message a fixed number (called the key) of positions in the alphabet. For example, if the key value is 2, the word "Sourpuss" would be encoded as "Uqwtrwuu." The original message can be recovered by "reencoding" it using the negative of the key. Write a program that can encode and decode Caesar ciphers. The input to the program will be a string of plaintext and the value of the key. The output will be an encoded message where each character in the original message is replaced by shifting it key characters in the Unicode character set.

(contrast with SIMM) 3 answers What is the clock speed of CPU?The clock speed measures the number of cycles your CPU executes per second, measured in GHz (gigahertz). A “cycle” is technically a pulse synchronized by an internal oscillator, but for our purposes, they're a basic unit that helps understand a CPU's speed.
What is the type of memory whose contents are not lost if the power is turned off or interrupted?RAM stands for random access memory; a form of memory that holds its contents even if the current is turned off or disrupted.
