Little Bump wants to run Time limit: 1 Sec Memory limit: 128 MB Topic DescriptionXiao Convex evening like to go to the playground to run, today he finished two laps, he played such a game.The playground is a convex n-side shape, n vertices are numbered counterclockwise from 0 ~ n-1. Now the small convex random stand in the playground somewhere, marked as P point

Topic Description Transmission Door The main idea: a convex n-shaped, n vertices are numbered counterclockwise from the 0~n-l. Now a small convex random selection of a position in the polygon, marked as P point. The P-point and N-vertices are connected to each other to form n triangles. If the P-point, number No. 0, and point 1th form the face of the triangleThe product is the smallest of the n triangles,

Ln, if the Y value is positive infinity down, you can see a sub-segment of Li, it is said that Li is visible, otherwise li is covered.For example, for straight lines: l1:y=x; L2:y=-x; L3:y=0Then L1 and L2 are visible, and L3 are covered.gives a line of N, expressed as a form of y=ax+b (| a|,| b|InputThe first behavior n (0 OutputFrom small to large output visible line number, 22 is separated by a space, the last number must also

Surround the Treesproblem DescriptionThere is a lot of trees in an area. A peasant wants to buy a rope to surround all these trees. So at first he must know the minimal required length of the rope. However, he does not know how to calculate it. Can you help him?The diameter and length of the trees is omitted, which means a tree can be seen as a point. The thickness of the rope is also omitted which means a rope can be seen as a line. There is no more than trees.InputThe input contains one

Link In the last session of multiple schools, I didn't understand the meaning of the question at the time. I thought it was a probability problem and I didn't have to look into it. Official question For the first one he said, considering that the probability of a line segment with a length of L is 2L/(pI * D), we can understand that we do not know what we are talking about .. According to my initial idea, I want to enumerate the angle and calculate the probability based on the height difference

Translator's preface This blog is actually a series of replies from Uncle Bob to xreborner (in the previous blog, xreborner proposed a series of sharp ideas for Uncle Bob to protect C ++ rights ). Body I compared the time consumption of C ++, Java, and Ruby in a recent blog. One of the participants (xreborner) submitted a convex hull algorithm code. It took me a long time to study the pitfalls. I did not find myself in the dark until I drew the algori

I am not sure how this convex bag will be used in image processing, because it seems to be more about computing ry or graphics. However, as an algorithm, I feel it is necessary to study it.
