Hello Codeforces
Today I did not solve as many problems as yesterday, since I had other things to do. I only had time in the morning and evening, during which time I solved 3-4 problems. An interesting point — I came across one problem at level 800, but despite this I came up with a solution for it only after 2 hours. Although this task almost completely spent my desire, I liked it. Also today I decided to fully analyze which topics I need to improve, and I came up with the following list:
Greedy, constructive algorithms, data structures, bitmasks, 2 pointers and binary search, brute force.
We are waiting for expert opinions on these topics in the comments.
Plans for tomorrow:
Prepare and not fail Div.4, understand the topics listed above, continue to solve problems
