"Examination" graph on Round2 15/06/12

Four silly questions, but I still hung up nearly 100 points.

T1. Bare maximum spanning tree, and I didn't make the mistake for a long time because I didn't get 20 points.

/* Set the flag: Forget to output no solution live eating keyboard! It's wrong to forget to check at first.

T2. Isn't that the same as yesterday? Teacher, are you sure you read the title when you selected it?

T3. Bare state diagram to find the shortest path.

It feels like I'm still too. Do when I want to be a silly problem even specific how to transfer the requirements of nothing to see, with a feeling a mess, and then changed to die.

Obviously the code ability is not good to think of is not clear, how can be so capricious?!

Measured to 0 points, I do not believe, the result was the windows evaluation environment pits = = inexplicably.

Then still only 40 points, transfer state when a certain dimension will play out without a sentence, in fact, think about it will find this problem, but I did not go to think of special circumstances.

Playing the state chart is to consider the more non-crossing this issue, the concept is not strong.

Habits are really bad, so go down even noip are kneeling to have how miserable and miserable.

"Only the thought of code, is the code of the AC."

/* Flag: After you have to try to clear the code, at least think about the topic to ask me what my algorithm is clear and rigorous.

Hit the problem, do not think about the problem is really water or the like (the result is hanging). */

T4. The problem is that considering a single point of contribution is the shortest.

Very uncomfortable! At the beginning of the problem is wrong, I yy out of the problem is to consider the contribution of the side, found that after the switch over for a long time.

/* Stand down flag: After the topic meaning must see, CLJ said, "exam question face three times is not faster than who this few seconds", test instructions see the consequences of not clear to think very enchanted, after you find that you see wrong after it is difficult to jump out to rethink. */

Anyway, the topic is not enlightening, but there are many lessons, "lessons more important than experience."

Feel some things I have been more contempt, but the tease is his weak Ah, the convinced is to be convinced

Still have to face the problem, so that there may be real change

By the way, graph theory round3 is my question.

Anyway, I will have some interesting questions, or not too stupid

I really want to build a problem, but it's hard.

Sometimes I will yy a model, and then yy a solution, but maybe my solution is wrong

Own the result of the problem of self-marking to write ugly or something = =

It's too weak to be qwq.
