Question: Calculates the total area of the sum of N rectangles. Http://poj.org/problem? Id = 1151 Referring to the discretization pages in the black book, I thought of the polygon Filling Algorithm in computer graphics I learned last semester.

Atlanta is widely known and few people are seen on the street, only a few cars are running slowly on the road. The drivers here are very polite. Even if you violate the traffic lights and cross the road, they will stop very far and let you do it. This surprised me very much. fresh fruit, freshly squeezed pure orange juice, sweet pastries, meat-based lunch, always ice-based drinks and water. I slowly did not adapt to it. About 1 about people atte

= | It seems that it is long enough in the draft box ~~~~~ I wanted to write a detailed scanned line ~~~ However, I don't want to change the code. I can compare it with the code of other Daniel. I think this single-point update is simply a pure violent pseudo line segment tree ~~~ There is also the discretization. [if it is discrete, we still use the function to go to O (n) to find out what is going on. Hello !] If the scope of the question is 10000, it is estimated that I will go to where the b

Discretization: store all X axis coordinates in an array... sort. When entering a line segment, determine the discrete values corresponding to the left and right points by means of binary... Scanning line .. it can be seen as a straight line

Source: http://poj.org/problem? Id = 1151 Give some Rectangles and find the area of these rectangles. Idea: the question of Line Segment tree + scanning line. Because the data is double, discretization is required. Code: # Include #

Scanning line problems The first scanning line was followed by other people's code. The tree does not have much content, so it is not put into the structure. Map ing is very convenient and inefficient. // 0 Ms 368 K g ++ # include # include #
