Life's a garden. Dig it.
Here's your first challenge!
Design a data structure to represent an image. Don't worry about implementing it in code. Just think about how you'd do it.
Would you use an array? A list? A graph?
Would you store integers? Booleans? Floats? Perhaps a combination of all three?
Would you represent highlighly detailed images like a field of grass in the same way you'd represent simple images like a red square on a white background?
The goal of this challenge is to get you thinking about the intricacies of image representation and storage.
