Observation / Thinking problems
By buihoatpt1874, history, 4 years ago, In English

Hello Codeforces community ! Recently I found out that I am very weak at problems that require quick and precise observation, like 1330D, like I always solve these kinds of problem way to slow or unable to solve them at all. Can you please suggest problems like that ? I know there is tags in problemset, but I believe good problems recommended by people who solved them will be more beneficial for me and other people aswell. Thanks in advance.

Almost all constructive algorithms' problems are based on observations.
Try to solve more of them.
Also, Atcoder problems are good.

Give lots of virtual contests...this will to force yourself to think and come-up with solutions.
