An instructor gives a series of exams during the semester in her math class. At the end of
the semester she drops each student's lowest test score before averaging the scores. She has
asked you to design a program that will read a student's test scores as input and calculate
the average with the lowest score dropped. Here is the algorithm that you developed:
Get the student's test scores.
Calculate the total of the scores.
Find the lowest score.
Subtract the lowest score from the total. This gives the adjusted total.
Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average.
Display the average.
The test scores are in a text file named scores.txt and contains the following:
Mickey, 71.0, 42.0, 83.0
Donald, 94.0, 73.0, 72.0, 81.0
Minnie, 95.0, 85.0, 45.0, 55.0, 65.0
A sample run is as follows:
Enter a file containing floating point numbers: scores.txt
Test scores for Mickey: ['71.0', '42.0', '83.0']
Removed the lowest score of 42.0 for Mickey

Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with
resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied
across each. Their equivalent resistance Reg is related to the values R1, R2, ...,
Rn by:

Write a program that prompts the user to enter the resistance of n resistors. The user should
be prompted continuously by using a while loop until a zero or negative value is entered (the
program should count the number of resistors n entered by the user and store the values in an
array). Use another separate loop to print the resistance values entered by the user and the
equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.

They are exhibiting this amoeba in a national. conference. They want to know the size of the amoeba at a particular time instant. If a particular month's index is given, write a program to display the amoeba's size.

You will implement a variant of the number guessing game we played in lecture. In this variant, you will ask the user to guess the price of a $42,500 car. Let's assume that the player knows the price of the car is rounded to the nearest $500. If a player's guess is not exactly correct, your program will tell them they are either too high or too low. The player will get as many guesses as they need to guess the price of the $42,500 car. However they will only win the game if they used 5 or fewer guesses. Here are two examples of how the program should work for both cases: Guess the price and win the prize! Enter your guess:50000 Too high! Enter your guess:40000 Too low! Enter your guess:45000 Too high! Enter your guess:42500 You won the car! Guess the price and win the prize! Enter your guess:46000 Too high! Enter your guess:45000 Too high!

An airline company has decided to apply a 10kg limitation for passengers' hand luggage and 20kg for their normal baggage. When passengers arrive, they enter their hand and normal luggage weight from the keyboard. If passengers exceed their normal baggage allowance of 10 dollars per gram, they pay 12 dollars per kg. Accordingly, write the program that calculates the baggage price of the airline they will go to according to the baggage values entered by the arriving passenger and keeps this from closing the program for each passenger. Note: If hand and normal baggage allowances are stretched below the maximum value, the payment amount will be considered not negative. An example printout is given on the right.
