EDIT:
I have made a second video!
Hey guys,
I have realized that most codeforces guides include something like doing more problems, or some strategy to help people practice. Instead of making a video like this, I have decided to make a new video series where I share some tips and tricks I have come across while solving the easier problems (Div. 2 ABC) in some unorthodox ways. This will include things like how to quickly guess and prove a solution, using sample cases to your advantage and learning some common ideas in these questions.
I have uploaded my first video in which I go over two questions, which are relatively tricky to find out where to start, but become much easier when you notice a pattern in the sample cases.
Please let me know what you think of it and if you have any suggestions please tell me so I can improve my videos in the future. Thank you!
The video looks good!
This video series will really be helpful for many newbies and pupils.
