pawn programming

Test instructionsThis day, Sjy seems bored. at home.On a chessboard, there are n black pieces. Every time he put a black pawn on the board. Either put on a white piece, assuming it is a white piece, he will find out the recent black pieces from this white piece.The distance here is Manhattan distance (|x1-x2|+|y1-y2|).Now give the nIdea: Kdtree first question.What is a kdtree?Now, for example, there are some points on the two-dimensional plane that we

continue to throw pieces Q1;。。。。。。If the pawn is not broken, then the pawn Q1 will be thrown to a layer greater than or equal to 100 stops: x+ (x-1) + (x-2) + (x-3) +...+2+1>=100, that is, x* (x+1)/2 of the minimum value, so that it satisfies the >=100, the solution gets x=14.ThatFirst throw from Layer 14 (break the test 1-13, need 1+13-1+1=14 times)Then throw it from layer 27 (break the test 15-26, need 2

BZOJ4563[HAOI2016] put a pawnTest instructionsGive you a n*n matrix, each row has an obstacle, the data guarantees that any two obstacles are not in the same row, any two obstacles are not in the same column. ask you to put n pieces (the position of the barrier can not play chess pieces), but also to meet each row only one piece, each column only a piece of the limit, ask how many kinds of programs. n≤200.The following:Find out where the obstacle is and the answer is irrelevant. So you can put t

There are n pawns on an N * n chessboard. Each time you move a piece up, down, left, or right, the last row, one column, or the Primary and Secondary diagonal lines (therefore, a total of 2n + 2 possible target States) require the minimum number of moves. There are some positions on the board that are obstacles and the pawns cannot go through at any time. The initial position of a piece must not be on the obstacle. Any two pawns cannot reach the same grid at the same time. [Input file] the fi

Object-Oriented design method: The basic idea of Java object-oriented programming is to solve problems by constructing and organizing objects. Objects are good, and any object can be considered an object, for example, a car is an object. The object has two most basic properties: it has certain material foundation and certain function, these two basic attributes in the Java language to have certain storage unit and have certain function. After understa
