Hi everyone. When i first started this job, i was thinking i'll be very successful if I study enough and enthusiastic. I spent so much time on learning this thing.I sacrificed my hobbies and sleep over code. However, it was too late i understood my epic failure. I cannot remember what i studied, cannot think practically, cannot solve problems properly. Now i am so upset that i wasted my time trying to learn programming. And i am giving up today. I am waiting for your advices and comments to inspire me return, although i know it will not happen. Take care of yourself. Signature: A faithful programmer...

I hate all the programming languages, problems, math and olympiad. I cannot stand Codeforces and MikeMirzanayov. Why the hell are you on the world? Why do you live , all of you ! You lose your time here. Go and study for YGS . I have 7 mistakes. Artıla murat.

Do you want to win a T-shirt? No , I dont . Do you want to learn how to design tasks for programming contest? No , I dont . Do you want to solve 7 tasks in 2.5 hours? No , I dont. So Codeforces Round #270 is not right for me. Have a nice day.
