Returns the prime number and Euler's prime number by linear sieve (Euler's sieve ). Time complexity O (n) WHEN n is large, the time used by the Euler's screening method is more and more obvious than the time used by the O (nloglogn) algorithm. Why? In the Euler's screening method, each sum is accessed only and the value of f [] is modified once. For (I = 2; I

Problem Descriptiona Ring is compose of n circles as shown in diagram. Put Natural number 1, 2, ..., n into each circle separately, and the sum of numbers in the adjacent circles should is a PR Ime.Note:the number of first circle should always be 1.INPUTN (0 Outputthe output format is shown as sample below. Each row represents a series of circle numbers in the ring beginning from 1 clockwisely and anticlockwisely. The order of numbers must satisfy the above requirements. Print Solutions in lexic

A number is a prime number (also called prime number). if and only when its approximate number has two -- 1 and itself. It is specified that the two approx. numbers cannot be the same, so 1 is not a prime number. The Study of prime numbers belongs to the category of number theory. You can see that many mathematicians c

Summary of filtering prime numbers: The simplest method to screen prime numbers isStart from 2, remove the multiples of SO 2, and then start from 3, remove the multiples of 3, and proceed in sequence.. According to this, it is easy to write the code. The code below is to screen the prime number method to obtain the prime
