I don't know if this happens with you guys but my brain functions just like the tides. Just like high tides it gains maximum power and I am able to think even the hard problems easily and just like low tides easiest questions take time and it's frustating from last two days. Just solved two good questions and felt like to do more and more. Happy Coding To You!

Lately i have been very active on Codeforces still can't find a way to reach above 1200. After reading so many guides and blogs to improve rating I am very confused.Please tell me what should I do. Thanks in advance.
