Topic: Given a black and white matrix, the largest black and white sub-squares and sub-matricesReverse the point of an odd position, then the largest sub-square and sub-matrix of the solid colorThe matrix is divided into layers, above each layer is a similar to the ▆▃▇▂▉, with a monotonous stack run out each point left to right can expand to the maximum distance, update the answer can be#include Bzoj 1057 ZJOI2007 checkerboard making monotone stack

Title: Give a matrix formed by 01, ask the matrix of the largest area of the square and the rectangle, any one of the squares adjacent to a different lattice.Idea: In fact, all (i + j) 1 in the position of the number XOR, it becomes all 0 or 1 of the largest squares and rectangles. The first question is water DP, the second question can be monotonic stack or hanging line. are very well written.CODE:#include Bzoj 1057 Zjoi 2007 checkerboard Production

Title Description Given a 4*4 01 chessboard, 1 represents a pawn, 0 represents a space, and a pawn 1 can be moved to a space next to or below four positions in each of the adjacent places. Then given your target chessboard, ask you at least how many steps you can take to turn the current chessboard into a target checkerboard state. input The first line enters an integer t, which indicates that there is a T group of test data. Next, we give a 4*4 of o

DescriptionIn a given shape of the chessboard (the shape may be irregular) on the top of the pieces, chess pieces no difference. If you need to place any of the two pieces in the same row or column in the chessboard, please program the chessboard with a given shape and size, and put all the feasible arrangement C for the K pieces.InputThe input contains multiple

The problem is simple DFS, yes, I did it for one hours.The problem is given a chessboard, which. is blank, can not play chess pieces, #是可以放棋子的位置. When placing a piece, only one pawn can be placed in the same row.Input N,kThen enter the N*n board, #或者. , how many ways to put the pieces.·· DFS (S,KK) indicates how many pieces have been placed in the first line.Of c

This topic and the eight Queen kind of question a bit similar, DFS passed parameters inside and so far put a few pieces, but the latter can also not pass, the line is must pass, through this to enumerate columns, the most important point is that this topic is asked k pieces of the placement method, K is not N, So if the current line is not satisfied with the condition, or in the backtracking process, the re

Why do I copy two pieces of code at the same time on the homepage and the picture can't flow? Copy Code code as follows: Because these 2 pieces of code are identical, conflicts occur. Simply modify the code for another piece of code. The red callout place needs to be modified. You try: Copy Code code as follows:

1. We slide to the main screen of the mobile phone to find the components we want to add to the main screen, and then two fingers are diagonal to the middle part of the figure as shown below.2. Then we click on the "small pieces" in the image below. 3. Then find "Weather" Here we hold "weather" do not let go, as shown in the figure. 4. Then the weather group to drag the day home on it. 5. Then we set up the city in the weather

In the last chapter we know how to deal with two important chess action, want to eat each other's pieces, first to move their own pieces. Now Walt shares with everyone, how to move the pieces.Want to move the pieces, on the page, first click on the pieces to be moved, and then click on the target location, if you can m

Just debut interview one to algorithm topic, A watermelon, keep the shape unchanged, cut 10 knives up to how many pieces! Reply content:To help you search for an answer: How many pieces can a watermelon cut into 100 knives? explain why. The essence of your question is how many blocks of space can be divided by N planes. Let's look at the following three questions: 1) n points can be divided into as many se

In practice, you sometimes need to import a large amount of data into the database and then use it for various program calculations. In this experiment, we will use step 5 to complete this process and record the time spent by various methods in detail. The tools used in this experiment are vs2008, SQL Server 2000, and SQL Server 2008. The methods in step 5 are respectively used to import 1 million pieces of data into SQL 2000 and SQL 2008, the experim
