1. Squares
by CodeChum Admin
Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this!
Instructions:
Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line.
Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition.
Input
Multiple lines containing an integer.
2 6 0
Output
Multiple lines containing an integer.

6. There are 32 students standing in a classroom. Two different algorithms are given for finding the average
height of the students.
Algorithm A
Step 1: All students stand.
gniwolldi odT
gaihnel vd
Step 2: A randomly selected student writes his or her height on a card and is seated.
Step 3: A randomly selected standing student adds his or her height to the value on the card, records the new
value on the card, and is seated. The previous value on the card is erased.
Step 4: Repeat step 3 until no students remain standing.
Step 5: The sum on the card is divided by 32. The result is given to the teacher.
Algorithm B
Step 1: All students stand.
Step 2: Each student is given a card. Each student writes his or her height on the card.
Step 3: Standing students form random pairs at the same time. Each pair adds the numbers written on their
cards and writes the result on one student's card; the other student is seated. The previous value on the card is
erased.
Step 4: Repeat…
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.

Once the formula is properly encoded you can use the code as much as you want without reprogramming it and you can share it with non-programmers without any trouble. This lab is an example of such a formula. Once you program it you won’t have to worry about the area of a circle again. Write and test a program that computes the area of a circle. This program should request a number representing a radius as input from the user. Use the formula 3.14 × radius2 to compute the area. Tip: There are a couple of ways to code an exponent. Look in the Operators unit for help (and you can’t use an x for multiplication). Tip: You will need to use the float data type to compute the remainder. The output should explain the results.
