I started practicing from round 1 and now I have completed about 150 rounds. Of course I did not solve all of the problems since some of them are too difficult for me...
Although the tutorials are very good, however I feel that sometimes it might be still a little bit difficult for beginners, like me, to fully understand, especially for many div1 problems. On the other hand, as the problems are quite interesting and we can learn many clever ideas and techniques behind them, I think discussion helps a lot for obtaining deeper understanding.
Therefore, if anyone is also trying to solve problems one round after another, you are welcome to discuss problems with me, especially for those problems that I have submitted and got accepted (well, after all, I don't know how to solve those that I have never submitted...)
I would like to share any ideas or techniques involved in each problem that I have solved. Hope that every one could reach 'red' someday :D
Hey! I find your approach to be interesting. My approach till now has been to solve problems in order from 500-currently rated problems and I think I'll follow the pattern until 1200 rated problems. Doing the 900 ones at present. I agree that this way there is not much you can learn until you reach the harder problems. Will probably start following your approach. Also, congrats on 150 rounds solved!
Well, I know that we might feel 'uncomfortable' when we try to deal with harder problems. But if we want to learn more, finally some day we have to try to solve them. Anyway, it is up to you to find your own best strategy Keep up practicing :D
To discuss problems I would suggest to take part in current contests. There is a big disussion thread for every contest.
And, as my experience, the current tutorials are usually better than the older ones.
Thanks a lot for your suggestion. I usually participate a 'real' contest after I have completed practice of several rounds, to check whether I have got improved or not. But it has been a long time since I took my last competition (about two years ago), and I decide to practice more before the next one. Anyway, thanks a lot.
You also have an extensive list of blogs for the early Codeforces rounds, would definitely refer if I participate in any of those rounds!
It will be my great pleasure if that could help litte :D

You can see the test case if you click 'click' to see test details.
Thanks!! Didn't notice we can see test details.
Hey! I was solving this problem from the recent contest https://codeforces.net/contest/2009/problem/F and I got a wrong answer at test 5. I am sure i handled any overflow issues but other than that i am not able to find the flaw. Can someone help me . This is my submission https://codeforces.net/contest/2009/submission/280427504
I just changed some ints to long longs and it passed. Btw your helper function is brilliant
Thanks a lot. I completely overlooked them exceeding integer range. I thought this discussions site isn't active. Btw do u know any other discord servers or other sites which are active in CP discussions?
No unfortunately. I remember trying to find a CF Discord server but no success
No problem
I attempted the problem C of contest 973 (div 2). this is the link to the contest https://codeforces.net/contest/2013. This is my submission https://codeforces.net/contest/2013/submission/282220009. Not sure why it failed at test case 2. I am working with character arrays also because earlier with strings it was giving mle for the same logic (No idea why though). Can someone help me figure out what the flaw is?
