2015 Changchun Division Regional Tournament Summary

I really do not have the heart to review this painful memories.

I now really feel that for ACM, too, if love, please love deeply. Just superficial love is really conscience. So, for the last team to take iron, I explode zero of this experience, I really feel, think of giving up, but now just want to die knock, and as fate, continue to brush it.

First of all, say the warm-up, a total of four questions, our team three people each knocked a question. However, we all have to hit the problem, so we have to take turns to change the code debugging, the progress is quite slow, but also indeed by the Codeblocks compiler and Ubuntu system pit burst. Before coming to familiarize themselves with the system and the compilation environment, but did not fully adapt, so the various problems encountered before all reproduce, but also by the topic toss the dizzy, so in addition to flustered, only flustered. I knocked is greatest common divisor topic, for n is 100000,n^2 violence will certainly T's case, I think a lot, from the beginning is test instructions slowly by me, from the sequence of all the number of the greatest common divisor into the sequence of the first two number of greatest common divisor, that moment, I was collapsed, After the number of conventions on the basis of the table to find ideas, found the tree-like structure of the problem-solving ideas, but do not make a contribution, and then foolish thinking to open the 100005*100005 array, but obviously can not open, finally thought can be updated each time the node, and the resulting number is marked in the array, However, my method is still n*n, better should be n*m, each update node to get the range of the number is still between 1 to 100, so can be optimized to n*m, will not tle, but my n*n incredibly still has, but in the game after the end of two minutes to cross the question, Finally in the case of the results of the situation did not know how to get the volunteers sent the green balloon, finally know that they are still over.

But after the game only after this kind of thing, I really feel very powerless, after all, in fact, during the game I still burst 0, and others are short time, or is the strength of the crush AH. In addition, it is not enough tacit understanding, when we three people knocked three questions, but also to debug, at that time, in fact, should be more tacit understanding of the loss of a problem, such as the way the organizer claimed to be used to test the evaluation machine a problem, string processing problems. At the end of the game, the heart of a group of fire, a long time can not let go, I was particularly hate myself, but think of their own game during the whole people are trembling in the code, I feel very distressed, but also in the case of pressure to solve problems, my psychological quality is too poor, and this is because I am too weak. So really, only the strength is the hard truth, despite participating in the game, I still feel no strength, go or be abused.

The official race ...
