DZY loves Fast Fourier Transformation, and he enjoys using it.
Fast Fourier Transformation is an algorithm used to calculate convolution. Specifically, if a, b and c are sequences with length n, which are indexed from 0 to n?-?1, and
We can calculate c fast using Fast Fourier Transformation.
DZY made a little change on this formula. Now
To make things easier, a is a permutation of integers from 1 to n, and b is a sequence only containing 0 and 1. Given a and b, DZY needs your help to calculate c.
Because he is naughty, DZY provides a special way to get a and b. What you need is only three integers n, d, x. After getting them, use the code below to generate a and b.
//x is 64-bit variable;function getNextX() { x = (x * 37 + 10007) % 1000000007; return x;}function initAB() { for(i = 0; i Operation x % y denotes remainder after division x by y. Function swap(x, y) swaps two values x and y.
Input
The only line of input contains three space-separated integers n,?d,?x (1?≤?d?≤?n?≤?100000; 0?≤?x?≤?1000000006). Because DZY is naughty, x can't be equal to 27777500.
Output
Output n lines, the i-th line should contain an integer ci?-?1.

思路：因为b序列一定只含0或1，那么含0的是没有意义的
直接for就好了，然后用一个数组is[]记录前多少个b序列为1的位置
每次要找最大值的时候，如果is[]数组的个数小于一个常数，就枚举is数组
否则直接从大到小枚举最大值就好了
