"Number theory + Skill" Magic Noip simulation test the second trial T1 prime number statistics

. First talk about this problem, the problem of their own time to think, anyway, it is not all points, simply set the array smaller, get a sixty or seventy points. So began the violent screening method , the 1~m and 1~n of the prime numbers are screened out, and then subtract, just to note that N is the case of Prime, ans--; so he got 70.Positive solution: Such a large array must not, so need subscript (array) translation , the n~m and greater than sqrt (m) translation to the subscript 0~m-n.

Question: We will give you two equal-difference series, and calculate the number of common elements in these two series. Each series is given in the following format: n f d (representing the length, first item, and tolerances of each series respectively ). Ideas: First, an intersection of two series is obtained by extending Euclidean, and then the first intersec

The distance between CSU 1503 and the arc (question a of Hunan Programming Competition 2014)

. After finding the coordinates of the center, the next question is how to judge whether the link between the point and the center of the center is within the arc of the slice. I also used the situation to discuss it, however, there are still many cases. At the beginning, eight cases were divided, and then compressed to four cases: Determine whether the order of the given points is clockwise or counterclockwise, then determine the direction of the range, and then determine whether the point is i

CSU 1337 funny copyright Fei Ma Da's theorem (question J in Hunan Programming Competition 2013)

Question link: http://acm.csu.edu.cn/OnlineJudge/problem.php? Id = 1337 Solution Report: although the range of X and Y is 10 ^ 8, if A is greater than 1000, A ^ 3 will be greater than 10 ^ 9, in this way, there is only one 10 * C + 3 on the right of the equal sign, which can only reach 10 ^ 9 orders of magnitude. Therefore, no matter how many X and Y are input, we only need to take the range from 1 to 1000, enumerate a and B, then C can get, and then judge whether the range of C is between x and
