- The data type bool: Group of answer choices Can only be used in a selection statement. Can take on any expression as a value. Can take on values -1, 0 or 1. Can take on values true and false.State true or false: A regular expression enables a quick test to determine objects and text strings with undependable values.Extreme Fizz BuzzFizz Buzz is a classic Computer Science problem about Selection. For an integer x, print:• “Fizz” if x is only divisible by 3,• “Buzz” if x is only divisible by 5,• “FizzBuzz” if x is divisible by both 3 and 5,• the number x if it is not divisible by both 3 and 5.This problem is the extreme version of Fizz Buzz. You are given a list of K distinct integers A and a list of K characters S. Both lists are numbered from 1 to K. The integer Ai corresponds to the character Si. Denote B as the subset of A. There will be a rule for each possible subset: if an integerx is only divisible by all elements in B, print a string which is the concatenation of the corresponding character of each element in B, sorted by the index in ascending order. However, if B is an empty subset, print the first digit of x instead. Does it look complicated? Do not worry, as it is just a generalization of the regular Fizz Buzz. For example, if A = [3, 5] and S = [F, B], you will get the normal Fizz…
- Monty Hall Problem – Coding Lab In this lab, you will write a code that simulates the Monty Hall Game Show. Thegame host gives the participant the choice of selecting one of three doors. Twodoors has a goat behind them and one door has a prize. The set of choices arerandomized each round. The participant needs to select the door with the prizebehind it. When the participant selects a door, the game host reveals a door with agoat behind it. The game host opens a door (different from the one selected by theparticipant) that has a goat behind it. The participant is then given the option tochange their choice. When you run your code, the code would display a message prompting the user toinput their door choice, labelled as 1, 2, and 3. Then the code will display a doornumber (different from the one the user picked) with a goat behind it and ask theuser if they would like to change their choice. The code then displays a message onwhether the user guessed the correct door. The game then…Q1: Write a program that allows a user to enter a string containing a day of the week ('Sunday', 'Monday', 'Tuesday', etc.), and uses a switch construct to convert the day to its corresponding number, where Sunday is considered the first day of the week, and Saturday is considered the last day of the week. Print out the resulting day number. Also, be sure to handle the case of an illegal day name with an otherwise statement!In the class String, the substring method inserts a String into another String. -True or -False
- Question text Determine whether the ff hypotheses about a computer program • There is an undeclared variable or there is a syntax error in the first five lines. • If there is a syntax error in the first five lines, then there is a missing semicolon or a variable name is misspelled. • There is not a missing semicolon. • There is not a misspelled variable name. lead to the conclusion • There is an undeclared variable. Let the following symbols represent the corresponding statements: uv - There is an undeclared variable. se - There is a syntax error in the first five lines. ms - There is a missing semicolon. vm - There is a misspelled variable name. Thus, in symbolic form, we have to show whether the argument below is valid: uv V se se → (ms V vm) ~ ms ~ VM ... uvDIRECTIONS: Write the word TRUE if the statement is correct and if not, replace the underlined word(s) with the word(s) that will make the statement true. Example: Current that flows in a circuit can be limited using a transistor. Answer: transistor-resistor 1. Resistors can limit the flow of electric current. 2. Resistor is a passive device. 3. Capacitor can store electric charge. 4. Dielectric separates the two insulator sheets of a capacitor. 5. Passive device can be used as an amplifier.Rock Paper Scissors Game Instructions In the game Rock Paper Scissors, two players simultaneously choose one of three options: rock, paper, or scissors. If both chose the same option, then the result is a tie. However, if they choose differently, the winner is determined as follows: • Rock beats scissors, because a rock can break a pair of scissors. • Scissors beat paper, because scissors can cut the paper. • Paper beats rock, because a piece of paper can cover a rock. Create a game in which the computer randomly chooses rock, paper, or scissors. Assign the number 1, 2, or 3 to represent one of the three choices. Let the user enter a number. Then determine the winner by comparing the user input and the randomly generated choice of the computer. Additional instructions: • The Program should validate all user input. • Game should ask the user to play again and continue if yes and stop if no. • Once the user stops playing, program should print the total number of wins.
