Question link: Click the open link Question: Dominoes should be placed on a straight line. Input n, l, R To place n rows, the probability of moving down to the left is l, and the probability of moving to the right is R. You can adopt the optimal strategy, that is, you can place a segment in the middle, and then place a segment on both sides of the left and right. The placement order is arbitrary. Q: The expected number of times to place n cards under

produced by the rich farming nation and establish an effective administrative system, so as to successfully turn the overall national strength into a powerful and effective national defense force. His success in this respect outshines the kings of future generations. No one except Tang Taizong can stand against him in this respect. Thanks to the efforts of Emperor Wu and later Tang Taizong, the time for the northern grassland to conquer the central plains was extended by more than 1380 years. I

Many of the recent topics are related to the Fabonacci sequence, and as an information group Konjac Konjac I have recently talked with the math group Lee a great God (Orz), including some of the nature of the Fabonacci series, to make a summary here.Resources:"Combinatorial Mathematics (5th Edition)", "Specific Mathematics (2nd edition)"Body:The Fibonacci sequence is shaped like 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ... of the sequence. The recursive form is defined as:Sequence f[n]=f[n-1]+f[n-2], whe

Use characters ' 3 3 ... . *. ... Output Not unique Input 4 4 . ** *... *.** .... Output Input 2 4 *.. * .... Output *Input 1 1 . Output Not unique Input 1 1 * Output * Note In the There are indeed two solutions: and ^ So the answer are "not unique". Title: Given a n*m black and white matrix, ask if there is

One night, after producing the drawings in his ' Toilet series ' (where he had to use his toilet paper to draw on, for all O F His paper is filled with squares and rectangles), he dreamt of filling a large rectangle with small rectangles of width 2 and Height 1 in varying ways. Expert as he is in this material, he sa

What is vertical storage? How does this new technology improve storage capacity and stability? Have you ever heard of the Super Paramagnetic effect (superparamagnetic effect)? This is a theory that limits the size of available hard disks. (e.g., no more than 120G, etc.). Simply put, when the magnets on the disk become too small, they will not be able to maintain the correct orientation of the magnetic field at room temperature, resulting in a null bit. Empty bits = missing data = useless storag

Click Open Link Question: There are two kinds of dominoes: 1*2 and 2*1. How many paving methods can be used in a rectangle filled with M * n? Ideas: In binary format, two consecutive 00 indicates that the two grids are horizontal, and 1 indicates that the grids are vertical (the upper part or the lower part of the bone card ). First, process and obtain all the statuses that meet the condition. If there is 0, two zeros must appear consecutively. For

quality. As we all know, spider uses the Web to capture insects, because each node in the Web is interconnected with each other, which increases the toughness of spider networks and is not easily broken through by insects. The object-oriented approach is to reuse code and ensure stable operation, that is, to reduce connections between modules. As you can imagine, it is not easy to reuse code if the links between modules are too close, because it is difficult to find the same suitable environmen

In a checkerboard consisting of 2 ^ k * 2 ^ k Square, there is a square occupied, and the four L-shaped bone cards are used to cover all the squares on all the checkerboards, which cannot overlap. The Code is as follows: def chess(tr,tc,pr,pc,size):global mark global tablemark+=1count=markif size==1:returnhalf=size//2if pr N is the checkerboard width and must be 2 ^ k. n = 8 in this example.
