What is the main goal in a Karel challenge?

The main goal in a Karel challenge is to instruct Karel to complete tasks in a grid environment. This involves writing commands and using programming concepts to navigate Karel through a specified area, enabling it to perform various actions such as moving, placing, picking up beepers, and responding to the environment effectively. The challenges focus on developing problem-solving skills and understanding programming logic, allowing learners to engage with fundamental coding principles in a practical, interactive way. The environment itself is generally a grid consisting of beepers and walls, requiring thoughtful planning and execution to accomplish tasks efficiently. This directly contrasts with activities like solving mathematical equations, programming advanced algorithms, or playing games, which do not reflect the primary aim of manipulating Karel in a grid-based programming context.
