Question: Determine whether An AND An-1 are equal. N is divided into two situations -- 1. n is a prime number, 2. n is the sum. = It seems like a piece of nonsense .. When a prime number is used, no can be directly output, because the prime

by c = 2 (n = 10) 2-32 (mod 10) Wilson's Theorem When and only when P is a prime number: (p-1 )! Interval-1 (mod P ). In short, the number between {2 .. P-2} can be paired by two. The product is the same as the 1-module p. Therefore, the concatenation part can be changed to 1, with only 1 * (PM) left. The last formula is used to verify the result. [But why can

Approximate test instructions: given [l,r] interval, find each prime in the intervalData range:1R-l 1,000,000.R value is too large, so can not directly sieve [0,r], to space and time optimization, using the interval sieve method, but also note that can not use int, because R and L are full int, the middle has a lot of detail processing will explode int, also note that 1 is not prime, so in the interval siev

This is a classic question about the prime number of secondary screening. Given L, U, in L ~ The distance between two adjacent prime numbers in the U range is the greatest and the distance between the two adjacent prime numbers is the smallest. The range of L and U in the question is 1 ~ 2,147,483,647. But the question
