For a long time, I was troubled by this sudden difficulty. I was also worried, and I didn't know what is waiting for me.

It seems to be a long time to write this thing, but I always feel that I have no improvement. It is not to say that I have no solid foundation, nor I don't have a good knowledge. It seems that the lack of lack is a smart big head.
Just finished the warming game, it's better to say that it is hot. Sweat! Uncomfortable! 5 hours of answers are really a test. I picked a topic that I thought it was very good. I remember that when I learned the triangle function: an arch bridge, there is water below, the water surface width is W, the arch is L, I would like to accept the highest allowed to pass the bridge? However, this book is killed, I think this topic is too E: a columnar material, elongated, length L, expansion can occur in the case of heat. The formula is L '= (1 n * c) L [L' is the length of the expansion, and N is an elevated temperature, C is expanded. Then you know the original length, if the material is horizontally between 2 wooden boards, then heat, generate an arched change. Then calculate, the top of the arch is raised from the original horizontal position! ! ! ! !
I am talking about the idea of school, you are talking about it. But it is really different. First, you will definitely think that this is certain with a circle and the corresponding triangle function. So, you must think of the arc length and angle problem S = N * pi * r / 180, then 2 unknown numbers, the center angle A and the radius R. At this point you can easily derive the equation A = 2SIN (A / 2) * [1 N * C]
Ok, this is my idea, I am attributed all things as this one-yuan equation. This is very simple, but an angle and the sinusoid of the corresponding half-angle, how do I solve it? ? ? ?
In fact, my teammates also encountered similar problems while solving C issues. It is to say that this is the bottleneck of these weird problems. Once you break through, you can complete the design of the entire algorithm, but these things make you and successfully shoulder . We can always see the substance of the problem, and we can also analyze solutions, but many basic problems have really plagued us.
Another important place in this warm-up is that team spirit and strength are far more than personal. It is important to know this problem. Therefore, in the warm-up match tomorrow, try to take the idea to discuss development, we tried, 2-2 groups, or hodgepodge. I believe it will have a good result.
But in any case, relative to the first time, I feel that it has greatly improved from the programming ability or the idea of solving the problem. This is going to be a good sign. But it is imaginating. keep working hard!
Summary: 1. Team Design 2. Calm Solution 3. Foundation Problem 4. Good signs
