You don't have to learn anything in particular to solve Div. 2 B, just practice more and maybe a little bit harder problems.
like can u suggest me range in which i should be solving question?
1000/1100
50 random mediums on leetcode
i have more then 50 medium on leetcode random
div2B is almost equal to leetcode medium, if you cant solve B in ~1.5 hours try to set a timer when pratice maybe it helps
when you able to solve medium in ~40 min in average, you should be able to solve B in contest time
leetcode and codeforces problems are vastly different in my opinion tho. You can be really good at leetcode mediums (theyre really simple and straight to the point) and still fail miserably at constructive/binary string problems
do more virtual participations and consistently solve B and C problems. Also make sure to upsolve one or two problems after a contest.
i upsolve one problem after the contest
Div2 B problem often Math/Greedy/Implemtation. Then you should try to practice that type of topic more :)
Read this pdf from Masataka Yoneda .
Just try to do some difficult problems and you will succeed!
You said in one of the comments that you have >50 leetcode mediums, so that means basic logic building you know, so now just take TLE eliminators sheet and start solving the 1200 rated problems one after another. Trust me it will help a lot. The link is here -> https://www.tle-eliminators.com/cp-sheet
Good Luck!!
once done with 1200 move to 1300,then 1400 and so on.. at the same time practice standard probs and algos from time to time
