Title Address: 51Nod 11351. The original root definition: Set M>1,GCD (a,m) = 1, so that the minimum set of R, called a pair of modulo m of the order.2. Theorem: If modulo m has an original root, then he has a total of the original root.3. Theorem: If P is prime, then the prime number p must have the original root, and modulo p of the original root is a.4. Theore

primes (prime number)Also known as Prime number, refers to the number of natural numbers greater than 1 , except 1 and the number itself, can not be divisible by other natural numbers (can also be defined as only 1 and the

I once went to a company interview, encountered such a topic: ask for the number of primes within 1000 how many? Use multithreading to achieve, and give time to consume. I thought for a while and didn't come up with a multi-threaded solution. Today because of the opportunity, I talk about my solution.This problem obviously has to consider two questions:1, multi-threaded issues2, algorithm performance problemsSome people think what algorithm performanc

Http: // 162.105.81.212/judgeonline/problem? Id = 1150 Question: Ask the last digit of C (n, m) not 0. N! /(N-m )! This is a classic data topic. I have learned a lot but I can't do it myself. Next post: Analysis of the four-dimensional space blog. How can I solve this problem? Don't worry. Let's discuss the following sub-problems:1. How can we find the number of occurrences of X (for example, 5) in the N factorial?For example, 15 factorial: 1*2*3*4*5*

1. Thinking of solving problemsAccording to the requirements of the question, the input data first to determine whether there are 22 of the same data, and then the order from small to large, because it is not related to the prime number, the set of any one of the logarithm is not a prime correlation, I use sequential traversal, the set of each

Pat math prime Link: http://pat.zju.edu.cn/contests/pat-b-practise/1007 Let's define DN as: DN = pN + 1-PN, where Pi is the I prime number. Obviously, d1 = 1 and for n> 1, dn is an even number. The "prime number pair conjecture"

HDU 1431 Prime Number Someone asked me this question. I personally feel that the violent search will be TLE O (n * sqrt (n )). N = 100000000; (2 ~ is used to determine the prime number ~ Sqrt (n) + 1 removal) The enumeration is better. Enumeration 1 ~ 10000. Save each of them. The
