Consider starting from $ ($) $ to search the mobile scheme, each time the change in the coordinates is $2$.If a ring is formed, then the perimeter of the ring must be even.Consider that the ring must be covered by a number of dominoes, and there is a location that is empty.So the circumference of the ring is an odd, contradictory, so the search will not find the ring, which will get a tree with a root.So the answer is all the key points plus the root

Test instructions: To a m*n chess board, there are K lattice has a hole, with 1*2 dominoes to cover the board, each lattice must be exactly covered once, there is no place to cover the hole, ask whether there is such a scheme.Idea: It is easy to think of the lattice point as the point in the dichotomy, domino as the edge in the dichotomy (when the domino may be placed), the maximum match of the binary graph, if the matching number and n*m-k equal, the

Test instructionsGive a domino, to the left and right down the probability, to put good n dominoes, need to place the desired number of dominoes.Analysis:Using the idea of interval DP, if a position on the right side of the domino has been put, consider, put the middle of the situation,Dp[i] means put the first domino, to put the desired number of times, enumeration 1-i, each point to do the intermediate point to seek the corresponding expectations, t

after the other, just like dominoes. The final panic chain executes to the top of the stack, and then the program crashes. A good place is all the defer methods are executed in the panic sequence, and they can stop crashing.The following test method invokes the built-in panic method and recovers from this call:Take a closer look at the defer method: Defer func () {fmt. Println ("Start panic defer") if r: = Recover (); R! = Nil {fmt. PRINTLN ("

Game theoryDoes this count as game theory ...?Orz ZYFSo sad ... Nest IQ is too lowHandling:When n is an even number, it can be completely covered by the 2*1 Domino, so each time you go to the other end of the domino, and the other person can only walk the new dominoes until there is noWhen n is an odd number, the first lattice can be completely covered by the 2*1 Domino, so the outcome is reversed.Qaq IQ Catch an unexpected AH unexpectedly1 /*********

On javaeye, I saw 10 things that YY most wanted to do in the IT industry. I felt that the intensity was too small. YY yourself:1. FTTH optical fiber is required for access, and at least 1000 m lan is required.2. Google launched a new super easy-to-use operating system with ultra-high efficiency and no historical burden. The size is only 40 MB.3. All software is used on demand through broadband, no installation is required, and charges are collected based on the time of use.4. If the home compute

In a checkerboard consisting of a 2^k * 2^k, there is a square that is different from the other, and how to cover the other squares of this particular square, using the following four kinds of L-shaped dominoes.Four L-type dominoes such as 1Figure 1 Special squares in the chessboard 2Figure 2The basic principle of the implementation is to divide the chessboard of the 2^k * 2^k into four 2^ (k-1) * 2^ (K-1), the special squares must be in one of the su

There are often many examples in mathematics: A complicated mathematical problem is proved by a very delicate and concise method. These proofs often reflect the subtlety of mathematics, which is incredibly impressive. Let's look at a classic example: if there is an 8*8 chessboard, two grids are removed. Can I use 31 1*2 dominoes to cover the entire board.I believe many people know the result. The reason is clear: we have colored the entire board wit

advantage of C is its versatility and portability, while leaving most of the control on the hardware layer to the assembly language. For example, C programs can be compiled and run on the following devices, HP 50g calculator ARM processor), TI-89 calculator 68000 processor), Palm OS Cobalt smartphone ARM processor), the original iMacPowerPC), ArduinoAtmel AVR) and Intel iMacIntel Core 2 Duo ). Each of these devices has its own proprietary assembly language and is completely incompatible with th
