I ran my best during this holiday and completed the first round. (Of course I should review, right???) Debugging is a basic programming skill that must be learned, but it is not covered well in most lectures. Through this lecture, I learned various tips that not only help me find errors, but also help me easily understand the logic of complex code. After listening to the lecture, I feel that programming without learning debugging is like going on a new path without a map or navigation. Thank you so much for making such a great lecture. ^^
