I do not know how to disappear, Bzoj has no 3687 of the problemTest instructions: give you a n and then enter n number to find the XOR of all subsets of this n numberIdea: Using Bitset to record whether a number appears in a subset and in the Bitset, using the fast and large number of operations (shifts) of the bits, by the subset already found and by finding out the remaining subset andReference code:1#include 2#include 3#include string.h>4#include 5#include 6#include 7#include 8 #definell Long

When you create an expression for a filter, enclose the string in single quotation marks:"LastName = ' Jones '" characters below are special characters, as explained below, if they are used in column names, they must be escaped: \ n (newline) \ t (tab) \ r (carriage return) ~ () #\/=> Use of compute in the dataset

Test instructions is a world with many countries, each with n buildings, including a power station and N-1 buildings, all of which are surrounded by a convex hull that is the size of the country. A missile that explodes within a country can cause the country to power down.Step 1: Find the convex hull of each country (I use the horizontal sort is all kinds of pits, change the fork by the sort before, mainly is the back area of the time need this fork to sort information).Step 2: Determine whether

The main topic: give some points on the plane, ask these points in any of the three points of the triangle of the area and how much.Idea: Look at the data range only algorithm series. Since each triangle has three vertices, the violent words should be O (n^3) time complexity, obviously timed out, but we only need to optimize it to O (N^2LOGN) can be solved.Well, the rest of the Guess, like O (N^2) enumeration, and then the rest of the Logn do nothing ...Again such as O (N) enumeration, and then

The plane gives you n (no more than 2000) points and asks how many of the rt triangles You can make up the area between [A and b].Enumerate each point as a right-angled vertex, sort on other point angles, sort by length in the same direction, and then enumerate each vector in turn, with its corresponding right-angled edge being monotonous, can be made with a pointer, and then the bands of those vectors in the same direction can be drawn (this code seems a bit problematic, may degenerate, It is a
