Odd-Even-inator
by CodeChum Admin
My friends are geeking out with this new device I invented. It checks if a number is even or odd! 🤯
Do you want to try it out?
Instructions:
- In the code editor, you are provided with a function that checks whether a number is even or odd.
- Your task is to ask the user for the number of integer, n, they want to input and then the actual n number values. For each of the number, check whether it is even or odd using the function provided for you.
- Make sure to print the correct, required message.
Input
1. Integer n
2. N integer values
6. Negative Decimal Tally
by CodeChum Admin
We've been giving positive numbers too much attention lately, it's time to let negative numbers take the spotlight this time!
Instructions:
- Input four float numbers; they could be positive or negative.
- Only add all inputted negative numbers, and print its sum, up to 2 decimal place.
- Hint: The previous/latest topic is about if-else-elseif statements, but do we need one here?
Input
1. First decimal number
2. Second decimal number
3. Third decimal number
4. Fourth decimal number
Output
The first four lines will contain message prompts to input the four decimal numbers.
The last line contains the sum of all the inputted negative numbers, with 2 decimal places.

by CodeChum Admin
This one is a bit tricky. You're going to have to isolate each digit of the integer to determine which one is the largest, so good luck!
Instructions:
- Input a 3-digit integer.
- Print the largest digit in the integer.
- Tip #1: Use % 10 to get the rightmost digit. For example, if you do 412 % 10, then the result would be the rightmost digit, which is 2.
- Tip #2: On the other hand, use / 10 to remove the rightmost digit. For example, if you do 412 / 10, then the result would be 41.
- Tip #3: You'd have to repeat Tip #1 and Tip #2 three times for this problem because the input is a 3-digit integer.
Input
1. A three-digit integer
Output
The first line will contain a message prompt to input the 3-digit integer.
The last line contains the largest digit of the inputted integer.

The government announces a program to support a price increase of $30 per kg of
this grain, which imposes a price floor of $730.
A. What are the equilibrium price and quantity before price support policy?
B. What quantity of grain is purchased by the consumers, supplied by the
producers and purchased by the government at the support price?
C. What is the change in consumer surplus, producer surplus and total surplus?
What is the cost of government to implement this price support policy?
D. Later on, the government changes the price support policy and provides
subsidy of $20 per kg sold. What is the price paid by buyers, price received by
sellers, change in consumer surplus, change in producer surplus and

We've been dealing with integers too much, it's time for float to shine!
Instructions:
- Input five float numbers.
- Print out the float numbers in one line, separated by spaces, and make sure you only print up to 1 decimal place.
- Add the first four float numbers and check if their sum is greater than the fifth float number. Print out "Yes" if they are.
Input
1. First float number
2. Second float number
3. Third float number
4. Fourth float number
5. Fifth float number
Output
The first five lines will contain message prompts to input the five float numbers.
The next line contains the inputted float numbers.
The last line contains "Yes" if the condition is true.
