题目大意:有N个花瓶,刚开始每个花瓶都是空的,每个花瓶只能放一束花,现在有两种操作
1 x y:收到了y束花,要求从花瓶x开始放过去,如果花瓶不够,多的花直接丢弃,输出放的花瓶的起始和终点,如果一个花瓶也没有,另外输出
2 x y:[x,y]内的花瓶清空,输出清空了几个花瓶

解题思路:维护区间的空的花瓶的数量,第二个操作就比较简单了,现在讨论第一个操作
首先判断一下,区间是否有花瓶(特殊情况),如果没有,直接另外输出
接着判断一下空的花瓶的数量和收到的花的数量,取最小值
最后,二分查找第一个空的花瓶所在的位置和最后一个花瓶所在的位置,找到这两个位置后,Modify这两个位置内的所有花瓶即可
