[NOIP2016]蚯蚓 乱搞

Description
你有n个线段，每一秒你要拿出来最长的一个线段切成两段长度为$\lfloor p\ast u\rfloor$和$u-\lfloor p\ast u\rfloor$两段（其中u是线段长，p是一个大于0小于1的实数）没被切的线段长度加q。问和第k秒的切割线段切割前的长度和m秒后的n+m条线段的长度。

Sample Input
3 7 1 1 3 1
3 3 2

---

Sample Output
3 4 4 4 5 5 6
6 6 6 5 5 4 4 3 2 2

我们开三个序列维护。
第一个序列存原数，第二个序列存$\lfloor p\ast u\rfloor$，第三个序列存$u-\lfloor p\ast u\rfloor$。
每次取三个队列队头最大值即可，易证不说了。
