4. ChatGPT can easily identify edge cases

One of the most significant challenges we encounter while solving LeetCode problems is that even though our solution method is correct, it might not pass some of the unit tests.

It can be difficult at times to identify which unit tests our solution is failing. If you encounter such a situation, the process to follow is quite simple. Just explain the problem to ChatGPT, describe your solution approach, and mention that your solution is failing on some test scenarios. ChatGPT will quickly grasp your intention, understand your issue, why it’s failing on certain test scenarios, and provide you with the most accurate response.

5. ChatGPT can easily identify the reasons behind Time Limit Exceeded and Runtime Error issues

The another challenge encountered while solving LeetCode problems is when our solution takes too long and exceeds time limits or when it encounters runtime exceptions.

In solving such problems, the ultimate goal is to find a solution under specific conditions, and time complexity is one of these limitations. If our solution is taking too long, utilizing excessive recursion leading to elongated processes, or getting trapped in an infinite loop, or if we’re facing runtime exceptions that prevent completion, understanding the root cause on our own can be challenging at times.

In situations like these, as mentioned before, we can once again present the problem and our solution approach to ChatGPT. We can ask it where we are encountering the Time Limit Exceeded or Runtime Error issue, which part of the code is causing it, and how we can address it. ChatGPT will readily provide us with support in a prompt manner.

6. ChatGPT accelerates our learning processes.

Considering the reasons we’ve discussed so far, it can be said that the least favorable aspects of LeetCode problems are their tedium and time consumption.

Naturally, if we aim to improve ourselves while solving a problem, we should initially strive to solve it on our own, make mistakes, and identify the reasons behind those mistakes in order to enhance ourselves based on these insights.
