Given a + bi, determine whether it is a Gaussian prime number, I = SQRT (-2 ).
Train of Thought: the common Gaussian prime I = SQRT (-1), the judgment method is:1. If A or B is 0, judge another prime number in the form of 4 * n + 3 (using the squared theorem of ferma)2. If n

Question Link
Find out how many K-tuples exist between A and B, and subtract the first element from the last element to S.
Idea: First screen out the prime number of SQRT, and then use these prime numbers for each interval to screen out the prime number of the interval, and then perform twopointer

Evaluate the prime number. This is an "old" problem. Everyone who has learned programming should have encountered it. Here is the classic problem of finding the prime numbers from M + 1 to N, of course, you have to write it down. The following are the questi
Question: determine the number of prime numbers between-and output all prime numbers.
Program Analysis: first understand what is a prime number, only the number divisible by 1 and itself, traverse the number between 101 and in a loop, and then use ~ For example, if the number is 200, we divide the number from 2 to 2 ~ The number between 112, as long as the intege
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 number cannot be equal to An-1. If n is the power of a ^ B when the number is combined, it is also NO. The reason is very si

At first glance at this topic, I think it may be difficult to see not very understand, but look at the given hint after the idea is very clearConsider the first sample. Overall, the first sample has 3 queries. The first query L = 2, R = comes. You need to count F (2) + F (3) + F (5) + F (7) + f (one) = 2 + 1 + 4 + 2 + 0 = 9.The Second query comes L = 3, R = 12. You need to count F (3) + F (5) + F (7) + f (one) = 1 + 4 + 2 + 0 = 7.The Third query comes L = 4, R = 4. As this interval have no

Prime numbers are also called primes. A natural number greater than 1, if not divisible by other natural numbers except for 1 and itself, otherwise known as composite numbers. According to the basic theorem of arithmetic, each integer that is larger than 1 is either itself a prime number or a product of a series of prime numbers, and if the order of these primes
