To illustrate the problem-first approach, let us consider a practical example. Suppose we need to find the shortest path in a maze represented by a 2D grid.

1. Understand the problem: Define the start and end points, and ensure that only open corridors are accessible.
2. Design a plan: Use a suitable algorithm, such as the dental email list graph theory Breadth-First Search (BFS) , which is ideal for finding the shortest path on an unweighted grid.
3. Validate the plan: Check the algorithm with a small maze to ensure that it works correctly, considering cases such as blocked paths or identical start and end points.
4. Write the code: Implement the BFS algorithm in the chosen programming language.
5. Refactor and optimize: Review the code and try different mazes.
Conclusion
"First, solve the problem. Then, write the code" is a guideline that reinforces the importance of problem-solving in software development. Taking a problem-first approach not only produces more robust and maintainable code, but also allows for more effective solutions that are aligned with user needs.
