For @Leetcode, I attended this platform since late 2019 and kept practicing till now. Actually I was not a CS students, I didn't learn any code language in my student life. But because of this friendly platform, I can learn DSA systematically and easily. Leetcode really help me a lot to improve my DSA skill in the past 2 years.

I also attend Leetcode Contest for 2 years, but in recent months, I found the contests' problems become easier and easier, and the problem quality become much worse than before. Compare to the earlier questions, the same level questions become much easier. In contests, for the second and sometime even for the 3rd question, if you do not label them as medium level, I would rank it as a easy level. And for the 4th question, why can you say it's a hard level question if 2K or even 3K people can pass it during the contest?

I know it's a commercial platform, and most people here focus on interview performance instead of they love to solve hard problems. But if you hold contests, I still wish you can maintain the quality of problems and contests.

For Biweekly Contest 78, I also did not finish the problem in time.
But I like this contest, it's what a normal contest should be.
