Best Performance and Worst Performance

After the last blog, I participated in three contests: GP of Gomel (tourist's contest), SRM 708, and GP of China. The problems were very nice in all contests and I really enjoyed them. However, my performance was quite different: in SRM everything went very well and it was my best performance after the last TCO, but today I performed terribly (well, 17th in Open Cup is not bad, but given that the problems really suited me, it was terrible).

In SRM I was in a very strange situation. A few minutes before the end of the coding phase, I found that my solution may access to out-of-memory and fail. However, it worked on random tests and I decided not to resubmit - and luckily, it passed the systest!

In GP of Gomel, I solved seven tasks (B, D, F, G, H, J, K) quickly and I still had two hours to solve something else. In such situations, I usually read all problems and sort them by expected difficulties for me. The difficulty is estimated by the number of ACs (objective difficulty) and the topic (for example, I'm good at combinatorial/mathematical tasks, but bad at data structures). For me the topic is more important and after spending several minutes on each task I decided to concentrate on A and I because they looked the most interesting for me and no task was solved by many people - however I couldn't finish coding I in time and ended up with nothing.

In GP of China, after solving five tasks (B, E, F, G, J), I had more than 3 hours. Among the remaining tasks, I liked C/D the most and decided to spend 3 hours on them, but again ended up with nothing.

It seems I can quickly solve easy problems, but when the problems become harder I can't do anything. I seriously need to fix this tendency. Maybe I should try Div2 in next Open Cup? Anyway, I will upsolve at least four tasks (Gomel's AI, China's CD) in the near future and post here again. I believe I understood the solutions for these tasks now and they are indeed very nice.

  9. After being in relationship with him for seven years,he broke up with me, I did everything possible to bring him back but all was in vain, I wanted him back so much because of the love I have for him, I begged him with everything, I made promises but he refused. I explained my problem to someone online and she suggested that I should rather contact a spell caster that could help me cast a spell to bring him back but I am the type that never believed in spell, I had no choice than to try it, I mailed the spell caster, and he told me there was no problem that everything will be okay before three days, that my ex will return to me before three days, he cast the spell and surprisingly in the second day, it was around 4pm. My ex called me, I was so surprised, I answered the call and all he said was that he was so sorry for everything that happened, that he wanted me to return to him, that he loves me so much. I was so happy and went to him, that was how we started living together happily again. Since then, I have made promise that anybody I know that have a relationship problem, I would be of help to such person by referring him or her to the only real and powerful spell caster who helped me with my own problem and who is different from all the fake ones out there. Anybody could need the help of the spell caster, his email: drosedebamenspellhome@gmail.com you can email him if you need his assistance in your relationship or anything. CAN NEVER STOP TALKING ABOUT YOU SIR HIS EMAIL ADDRESS IS:drosedebamenspellhome@gmail.com CONTACT HIM NOW FOR SOLUTION TO ALL YOUR PROBLEM
