I've been solving Leetcode easy problems, but still do not have logic, I just wanna be Specialist.

I've solved around 200 Leetcode easy problems with or without help from the discussions. Still, I don't have the logic to solve most of the CF div2 a,b. What should I do now? It's been more than a year. Should I quite? Please help me decide.

You should practice A problems from the problem set, After solving about 35 A problems now I am able to solve A problem in div3 in some cases only so just get out of your comfort zone, start solving some harder problems than your level, You will start getting result soon.

Solve a lot of Div 2 A and B. Especially from the recent contests, since now they are a lot more observation based. And yeah, that is pretty much it.

Hello, look at my graph for motivation.

Go to codeforces problem set and solve at least 50 questions of each rating. Like 50 questions of 800 Then 50 questions of 900 and so on....

Also, add friends who are having bit more rating then you so whenever while giving contest if you feel like quitting then go and check friends standing and it will surely motivate you to give another chance to the problem where you were stuck.

Also, there are alot of cheating groups on telegram stay away from them don't even look for hint or whatever.

To solve div2a and div2b, you need to upsolve div2a and div2b.

This worked for me very well:

Step 1: Solve A2OJ Div2. ladder A: https://earthshakira.github.io/a2oj-clientside/server/Ladder4.html

Step 2: If, still unable to solve A: Practice 80, 1200-1300 Problems
breakdown of 60 problems:
10: Most solved (rated 1200)
20: Most Recent (rated 1200)
10: Most Solved (rated 1300)
40: Most Recent (rated 1300)

Practice more and sometimes solve problems backwards. Sometimes I can only solve div2C and not the rest. Look at number of solves mid contest.
