Problem Description
The hailstone sequence is defined as the integer sequence that results from manipulating a positive
integer value n as follows:
If n is even, divide it by 2 (using floor division)
• If n is odd, multiply it by 3 and then add 1
Repeat this process until you reach 1.
For example, starting with n = 5, we get the sequence 5, 16, 8, 4, 2, 1.
If n is 6, we get the sequence 6, 3, 10, 5, 16, 8, 4, 2, 1.
If n is 7, we get 7, 22, 11, 34, 17, 52, 26, 13, 40, 20, 10, 5, 16, 8, 4, 2, 1.
If n is 8, we get the sequence 8, 4, 2, 1.
As far as anyone can tell, this process will eventually reach 1 for any starting value, although
mathematicians have been unable to formally prove this property as of yet.
a. Write a Python function named hail () that takes a single integer argument. hail() should
print out the sequence of numbers generated by applying the process above to the function
parameter. This function does not return any value.
Friend's Party Circle:
There are a few friends living in the same area. They have a party every weekend and the place of
party change each week. It is always a difficult task to select a place which is nearest for everyone.
They all decided to take advantage of Computer Science to solve this problem.
Names of friends are Ahmed, Rehman. Careem. Basit. Dawood. Ghani, and Farid. Ahmed lives at
5 minutes' walk from rehman and at 10 minutes' walk from Careem. Careem lives at 3 minutes'
walk from Dawood. Rehman lives at 4 minutes' walk from Basit and 2 minutes' walk from Dawood.
Dawood lives at two minutes' walk from Farid. Ghani lives at 2 minutes' walk from Basit.
a. If we represent a graph G = V (V, E) in which set of vertices are home of each Friend and
an edge represents a path between two homes. Provide the adjacency matrix of directed
graph of the graph G.
b. In above directed graph G. You are required to devise an algorithm to find all possible
paths.
Summary
During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W:
W = 35.74 + 0.6215 × T - 35.75 × V0.16 + 0.4275 × T × V0.16
where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit.
Instructions
Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.

Conceptually it is not very difficult to write a program that solves a problem that you can solve yourself. The skill you need to acquire is thinking very precisely about how you solve the problem and breaking it down into steps that are so simple that a computer can execute them. I encourage you to first solve a few instances of a problem by hand and think about what you did to find the solution. For example if the task is sorting lists, sort some short lists yourself. A reasonable method would be to find the smallest element, write it down and cross it out of the original list and repeat this process until you have sorted the whole list. Then you have to teach the computer 1) how to find the smallest element, 2) how to write it down, 3) how to cross it out, and wrap this in a loop. Then continue this task breakdown process until you’re confident you know how to write the necessary program.arrow_forward

A customer books a boat for an evening event, and the company provides the sailing and serving crew and all the necessary food and drink for the event. The customer tells the company how many people will be attending, and the company must calculate how much food and drink to purchase and bring on board for the evening. The problem is that the company's employees have been calculating badly, sometimes running out before the end of the evening, and sometimes ending up with a lot left over. So, you have been hired by the Seattle Party Cruise Company to write a program to help employees properly stock their cruise boats for any given event. You need to write a command-line program that asks the employee how many adults, teenagers, and children will be attending the event. The program should then calculate how many soft drinks, glasses of champagne, slices of…arrow_forward

Before carrying out skydiving activities, Bibi will always ask the name, height, and age of the participants. Bibi's participants is always 2 people. To make it easier to remember their identities, Bibi gave them a paper to write down their identity. But because they are very enthusiastic in doing skydiving, they write their identity in a single line only (for both of the participants), so it wasn't quite neat and it made difficult for Bibi to see it, and resulted in the skydiving process being disturbed. As one of the organizer committee, you do not want this activity to be disturbed and plan to provide a program that provides their identity neatly to Bibi. Format Input Input consists of 1 line. It contains the identity of 2 people in a row Ni, Ti, Ui - the name, height, and age of the i-th participant. Format Output The output consists of 6 lines. The first line, "Name 1: N1".

Rock, Paper, Scissors This is your traditional rock-paper-scissors game, where two players select one of the three options and a result is produced based on their selection. For reference: Rock beats scissors Paper beats rock Scissors beats paper For this problem, you are to assume that two human players will play against each other and will input their choices accordingly. The input for each player will be in the form of buttons. Once a player clicks on a button, the rest of their buttons are locked in place (i.e. disabled). Once the other player selects their pick, the program outputs who won or if there was a draw. This isn’t exactly the most realistic way to code the game as it would be better if both players made their choice at the same time, but we’ll just have to chalk this up as a limitation for our exam. Aside from the game itself, the program should track the score of each player. Basically, if one wins, that…arrow_forward
