. 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.

Description
There are two string s,t of length n and consist only of lowercase letters, satisfying s and T happen to have K-bit difference. Q in all strings that happen to have K-bit different from S, T is sorted by dictionary order. Because the answer can be large, the die 10^9+7 output.
Input
The first row of two integers n,k.The second line is a string s.The third line is a string T.
Output
An integer line rep

This is also the question of hnu 12831.
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

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

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
