Observation / Thinking problems

Revision en2, by buihoatpt1874, 2020-04-18 18:12:53

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.
