Feel oneself recently lazy, dozen code, do the problem is less, the result is very slow, such as the previous will be a little short circuit now do are very slow ah, or quite unskilled. And today, when the shortest circuit is submitted, notice that the last time I submitted a question in HDU was exactly one months ago, I have to criticize myself ... TAT
Feel oneself still have too much not to Orz, listen to the students say out of algorithm name all feel good and strong acridine.
I now suddenly feel that, relative to other types, I still prefer the graph theory, that simply practice this bar, do not greedy to think of other, because the other I really very bad, and learn, spend more time on the results or do not come out, see a problem to see half a day can not understand.
Graph theory is also learning a bit of search, the shortest way, the smallest generation tree, there are many waiting for me to learn, such as I have not dared to contact the network flow Orz ... And I do a very small number of problems.
Let me start with a special practice of graph theory and plan at least one question per day.
Criticize yourself once more.
