Description In the Fibonacci integer sequence,F0 = 0,F1 = 1, andFN=FN− 1 +FN−2N≥2. For example, the first ten terms of the Fibonacci sequence are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ,... An alternative formula for the Fibonacci sequence is . Given an integerN, Your goal is to compute the last 4 digitsFN. Hint As a reminder, matrix multiplication is associative, and the product of two 2 × 2 matrices is given . Also, note that raising any 2 × 2 matrix to The 0th power gives the identity matrix: .

Question link: Http://acm.hdu.edu.cn/showproblem.php? PID = 1, 4471 Question meaning: Evaluate F (n ). When N is a special point NK Solution: When X is not a special point, use the basic matrix to quickly calculate the power of F [X]. when X is a special point, use another matrix and perform left-side shift. That is to say, according to the special point NK, 1-N is divided into many sections, one Section and one special point are calculated back and forth. Two optimizations: 1. Because the

Question: Can you obtain the nth Fibonacci number? 0 The output result mod32768 is too large. Idea: Generally, the methods for finding the Fibonacci series are recursive, dynamic, or rolling optimization, but the space or time complexity is too high, now there is an optimization algorithm that uses a matrix plus a rapid power to maintain the time complexity in logn. Initialize a 2 × 2 matrix. If the initial value is {,}, it indicates {A2, A1, A1,

Analysis:If we include the Fibonacci matrix, we will find that this is an equiratio sequence.Push down: S(g(i)) = F(b) + F(b+k) + F(b+2k) + .... + F(b+nk) // Set a = {1, 1, 1}, (curly brackets ind

HDU 2842 Chinese rings (with constant matrix + rapid matrix power) ACM Address: HDU 2842 Chinese rings Question:A Chinese ring, the K ring to be unlocked first needs to be unlocked before (K-2) a ring, and leave the (k-1) ring. It takes at least a few steps to unlock N rings. Analysis:If F (n) is set, the N ring is unlocked.1. Due to the game rules, the N-Ring cannot be completely unlocked at once, or n-1 N-Ring cannot be removed.2. First remove the N

HDU 2294 pendant (DP + matrix Rapid power dimensionality reduction) ACM Address: HDU 2294 pendant Question:Tuhao made jewelry for his sister. He had K kinds of pearls, n of each. To show off the wealth, he needed to use each Pearl. Ask him how many pieces of jewelry with a length of [1, N] can be made. Analysis:1 ≤ n ≤ 1,000,000,000 is terrible.First, consider DP. Obviously, you can think of the following:dp[i][j] = (k-(j-1))*dp[i-1][j-1] + j*dp[i-1][

. The square matrix of N + 2 rows is constructed because 2333 can be multiplied by 10 and 3. It is roughly as follows: 10 0 0 0 ...... 0 1 10 1 0 0 ...... 0 1 10 1 1 0 ...... 0 1 ...... 10 1 1 1 ...... 1 1 0 0 0 ...... 0 1 The required column matrix is roughly as follows: 23 ...... 3 A, 0 A 2, 0 ...... A n, 0 3 The correctness of recursion can be calculated and verified. Here, the matrix is completed through struct and operator overloading. Code: #include ACM learning process-hdu5015 233 ma

Address: HDU 2842 This game is a nine-serial game. Assume that the first N rings are to be detached. Because you want to meet the first N-2 are removed, so first to unload the first N-2, need F (n-2) times. Then the N to unload the need for 1, and then this time to unload n-1, and then before the N-2 has been removed. At this time, the first n-2 is removed and all installed on the required number of times is the same, because the removal and installation of the rules is the same. So we need F (n

Rapid mean Blur for image processing (box blur) The essence of Image Blur: From the Perspective of digital signal processing, image blur requires suppression of high-frequency signals to retain low-frequency signals, Convolution filtering is an alternative method to suppress high-frequency signals. Select a low-frequency filter Each pixel is used for low-frequency filtering, so that the overall effect is that a digital image is more blurred and shows

ways, such as random selection, predetermined decision paths, or direct control by intruders. 3. modularity of attack tools. The new attack tool is able to change quickly, either by upgrading or by replacing parts of the module, compared to a previous attack tool that only implements an attack. Moreover, attack tools can be run on more and more platforms. For example, many attack tools use standard protocols such as IRC and HTTP to transmit data and commands, which makes it more difficult to an
