It is really hard to read. Every book that analyzes the 2.4 or 2.6 kernel is bigger than a brick. So someone turned out the Linux0.01 version, an

is different from the result 136165306871056 that my program ran out. A little visual, the above slope optimization code is out of bounds (I don't know how to change it ......) The limit of w (I, j) can be as high as (50000-1 + 50000*10 ^ 7-0) ^ 2, it exceeds the 64-bit integer range (although it does not seem to have such big data ). After the code is modified, there should be no cross-border issues (to avoid multiplication of two large numbers, you can refer to the check function in the Code

Tag: Cross Product Link: poj 2318 There is a rectangular box with blocks and the coordinates of these lines are given in order, There are N line segments, the box is divided into n + 1 areas, and then there are m toys. The coordinates of these m toys are known and asked how many toys are there in each area at last. Analysis: from left to right, until you determine whether the online segment of the toy is in the clockwise direction, this requires the u
