CCC ’17 S3 – Nailed It!
Nailed It! is a CCC senior 3/ junior 5 question. The method to solve this is similar to Escape Room. The first thing to do to solve this problem is to create a list that measures that number of boards that are length N into the term N. Then, we…
Liquid Crystal Display – Remote Controll
Remote controll A remote controll uses something that can detect the numbers pressed on a remote controll. It is called the Infrared Receiver. Like in the name, the receiver uses infrared light, which cannot be seen by the naked eye, to detect remote controll signals. Liquid Crystal Display An LCD…
CCC ’20 S2 – Escape Room
For a Junior 5 question, Escape Room isn’t that easy. The brute-force method would be to use breadth first search and find factors, but that will almost guarantee the time will exceed the limit. To solve this, we will need to use a method that doesn’t require any calculations involving…
CCC ’21 S2 – Modern Art
Modern Art is a CCC problem. Notice that if you brush on a specific square for an odd number of times, it ends up being a gold square. If it is even or 0, it is a black square. Using this, we could create a table that has the numbers….
Air Conditioning
An air conditioner uses something called refrigerant. In a hot room, the refrigerant will take away the heat from the room. The heat will evaporate. The more the refrigerant contacts, the more heat it will take away. A compressor is another part of an air conditioner. If the refrigerant is…

Arduino Light Project
To make an Arduino Light Project, you will need: 1 Arduino board 1 breadboard 15 wires 7 220 ohm resistors 7 Light Emitting Diodes Connect them all where the lights are side-by-side. Then, use the following code: This should create a lot of flashing lights.
Mouse Journey
Mouse Journey is a problem that is related to simple math. Read the problem first. The logic is simple: the total number of possibilities is the number of possibilities for the one above and the one to the left. The start is 1, and the cat areas are 0. Now,…
