I posted about the traditional Japanese arithmetic problem ‘Crane-Turtle-Problem’ on the Discord ‘exercism-idea’ recently. I’m grateful for the insightful responses I received.
I’m still at the Easy track for Java and the Learning Exercise track for Python, and I don’t have the skills to create an exercise yet. However, inspired by the excellent hints I received, I’ve been thinking about what kind of exercises I could create. Feedback would be appreciated.
-
Practice with conditional statements and loops:
Implement an algorithm to determine the numbers of cranes and turtles using conditional statements and loops. -
Mathematical thinking and logic:
Analyze the problem using mathematical principles and logical reasoning to identify mathematical relationships. -
Recursion:
For example, consider solving the problem recursively by decrementing a given number while treating it as the total count. -
Object-oriented programming:
Create classes to represent cranes and turtles, define methods for each class, and solve the problem by creating a class that calculates the number of heads and legs for cranes and turtles.
I understand that Goals of the Exercise and Concepts Involved are necessary for exercises. Also, since I’ve only touched on a small part of all the tracks, I need to consider potential overlaps with other exercises. I apologize for taking up your time, but I would appreciate any advice on revisions or directions for my ideas.
