Fruitful problems that may improve your coding skills
By Tet, history, 5 years ago, In English

Hi CodeForces!
Problems below are sorted by difficulity, hope they will rocket up your coding ability...

Binary search
Data structures (incomplete)
DP
DFS
Graphs
Geometry
Bitmasks
DSU(hard)
special problems*

note : special problems are tasks which are effective when solved without reading the tags(they might be a bit harder too).

If you have any recommendations feel free to mention them in the comments section.
This blog will be updated on a monthly basis.
Special thanks to MhdMohammadi, M_H_M, KMAASZRAA and X_emad_X for finding these problems.

Also some people have complained that -Morass- has written a blog on the same topic, well the only difference is that this blog will be updated on a regular basis and you can access fresh tasks via this blog.

Sorry to say lots of people will reject your hard work for -Morass- blog.His blog is more well-arranged with lots of problem.

But I have a great idea for you that will makes your blog surely acceptable to everyone.Here is my idea:

When someone ask for any specific type of problem like binary-search problem/bfs/dfs problem everyone gives them lots of problem from lots of Oj like cf/codechef/timus etc.But nobody suggest onsite( icpc regionals or IOI or NCPC(National Collegiate Programming Contest ) ) problem.So I suggest you to gather topic wise onsite problem.

I think it would be great if you could sort the problems according to a learner's perspective so that new competitive programmers get to realize from where to start and can track their progress. Otherwise they will have to read problems one by one and observe their difficulty level and waste a lot of time in choosing which problem to solve now and which to postpone for later.

      Oh... maybe you are already working on it. I just mentioned it because I felt not all the problems already mentioned were sorted. But I see where you are going. Looking forward to a great list of sorted problems.

i think 843-A (sorting by sequence) would be a good problem to add as its simple and teaches nice concept.
