Enhancing LeetCode Problem Solving: The Power of Examples

In the past, my approach to tackling LeetCode challenges was hasty. I would read a problem and dive straight into solving it, often leading to misunderstandings and failing to consider crucial edge cases. However, from these mistakes, I learned a valuable lesson - the examples provided in problem statements should not be underestimated. They are invaluable resources that provide clarity to the problem and illuminate how data should be structured and stored. They also guide us in determining whether additional variables or helper functions are necessary.

Recognizing the need for a more systematic approach, I've since revamped my problem-solving strategy. I now approach each problem with a heightened sense of attention and precision. Instead of rushing into solving it, I take the time to read the problem carefully. I've found that this simple adjustment has drastically reduced my misunderstandings and improved my problem-solving success rate.

One of the key practices I've adopted is the use of diagrams. These visual aids help me illustrate the problem-solving process, making it easier to comprehend and strategize. By mapping out the problem, I gain a better understanding of its intricacies and how different elements interact. This, in turn, aids in devising an effective solution.

Moreover, paying close attention to the examples provided has been a game-changer. These examples offer more than just a glimpse of what's expected; they serve as foundational building blocks for the solution. They show us the ideal structure and formatting of data and reveal which variables are essential for keeping track of progress or storing critical information.
