Test instructions: Give some computer two-dimensional coordinates, connect two computers with the network cable long for their straight line distance plus the feet. Requires all computers to be connected to a string, how to connect, so that the network cable is the shortest, and the order from one end to the other end of the output of the connection between the two computer distance.Idea: It's easy to think of a brute force enumeration that makes all the computers in a whole array, the one with

"Title translation":Problem analysis: Because tasks can be executed in parallel, it is intuitively a task that takes a long time to prioritize deployment. But this to the topic also gives you the task of time, so easy to let people think more.There are only two possible cases for tasks x and Y, regardless of the time it takes to account for the task. X ends before y, and x ends after Y. Here it is discussed that X is done before Y.When x and Y positions are not swapped, the completion time is: B

Dollars Time Limit: 3000MS Memory Limit: Unknown 64bit IO Format: %lld %llu Submit StatusDescriptionNew Zealand currency consists of $, $, $ $, $ $, $ notes and $ $, $50c, 20c, 10c and 5c coins. Write a program that would determine, for any given amount, in how many ways that amount may is made up. Changing the order of listing does not increase the count. Thus 20c May is made up in 4 ways:1 20c, 2 10c, 10c+2 5c, and 4 5c.InputInput would consist

Title: Two-dimensional push box game, gives you the location of boxes, people and targets, the solution of the output problem (push the box and walk the path).Analysis: Search, Priority queue. Priority is: first of all to ensure that the number of words to push the box, followed by the fewest steps to walk.The second fork heap is used as the priority queue, and the BFS can be done on top.Note: Notice the enumeration in dictionary order direction when searching, otherwise WA ╮(╯▽╰)╭.#include

Only the same color can be joined together, asked whether to form a necklace.Idea: If a bead is regarded as a non-forward edge connecting two vertices, then the subject becomes the existence of the Euler circuit for the non-direction graph. For the graph, if the number of degrees are even and the graph is connected, then there is a Euler loop. Then start at any point and wa
