Do title
For the exercise, we feel a summer vacation still left a lot of questions to write, most should be the instructor lecture example, there are a small number of test questions. The tests do not complete the revised algorithm because there is not, or because the cancer does not question too. At the same time, also found himself still has a lot to learn algorithms should never learned never written, exercises and algorithms to try to stay during the holidays fill it.
In fact, at school I do question the efficiency of feeling good, basic enough to finish the day more (60 \% \) \ above questions, as long as we can still seize the time to write a lot of questions, is feeling more adequate moisture in the room, little by It affects the people around them.
examination
A few days there are in fact managed to get the last few days are okay, that is the middle of a few days test well. Probably because I made a stupid mistake should not be made of it (without knocking universal head? Disjoint-set not sentenced to heavy?).
But other exams still have several times felt pity, because several times encountered a small problem completely difficult but do not know why I did not expect, or even thought of then own their own ideas and fast denied exam. The basic thought belongs to positive solutions but still knocked violence, seems to have more than once or twice, you may need more practice exam examination room quality.
This training strategy examination room feeling a lot better, do not write the questions are a good knock on the violence, it is generally not low scores, especially when the league, this method should be a good time. But several accidents that may well pay would increase optimization violence, but because I do not want to add those little lazy optimization, feel no difference. We should remember that since writing the violence, put together with optimizations can think of, just make sure not to waste the time to do other problems.
Specific, the ability to push me feel a lot better mathematical formulas, also mastered many new skills: demolition divisible, distance transform algorithm, \ (Prufer \) sequence, and so on. But there are still many aspects that does not work: a combination still does not count, complex data structure that is easy to think, tree \ (dp \) all written in dotted rule (though \ (AC \) , but the time complexity seems a bit too right) and so on.
Well, the most serious problem is the combination will not count , \ (dp \) routine is not cooked .
There is a three cancer algorithms do not want to learn: polynomials, network flow, computational geometry (related examples trailer).

Note written questions efficiency, blog remember to update.
