Description
You are asked to answer the queries that the sum of the endurance of a consecutive part of the battleship line.
Notice that the square root operation should be rounded down to integer.
Input
For each test case, the first line contains a single integer N, denoting there are N battleships of evil in a line. (1 <= N <= 100000)
The second line contains N integers Ei, indicating the endurance value of each battleship from the beginning of the line to the end. You can assume that the sum of all endurance value is less than 2 63.
The next line contains an integer M, denoting the number of actions and queries. (1 <= M <= 100000)
For the following M lines, each line contains three integers T, X and Y. The T=0 denoting the action of the secret weapon, which will decrease the endurance value of the battleships between the X-th and Y-th battleship, inclusive. The T=1 denoting the query of the commander which ask for the sum of the endurance value of the battleship between X-th and Y-th, inclusive.

/*
题意:有 n艘战舰,每艘战舰都有一定的能量值,炮弹每次炮轰区间内的战舰,区间内战舰的能量值变为原来的想下取整的开方数,
然后查询区间内的战舰总能量 初步思路:addv数组用来储存这棵树上的节点被轰过几次,向上向下更新的时候不会写了,试一下笨办法单点更新更新函数,不能找
到满足的区间就更新,必须要跟新到叶子节点才能,addv数组现在的作用是记录 #错误:把case i漏掉了
