Description

Yaroslav and Points

题意翻译

**题意** 数轴上有$n$个点,每个点有个互不相同的初始坐标$x_i$,接下来有$m$个操作,每个操作是下面两种之一: $1\space p\space d$,将$p$点的坐标加上$d$,保证操作之后任意两个点坐标不同。 $2\space l\space r$,求$\sum_{l<=x_p<=x_q<=r}(x_p-x_q)$。 **数据范围** $n,m<=10^5,1<=p<=n,|d|<=1000$ $|x_i|,|l|,|r|<=10^9$

题目描述

Yaroslav has $ n $ points that lie on the $ Ox $ axis. The coordinate of the first point is $ x_{1} $ , the coordinate of the second point is $ x_{2} $ , ..., the coordinate of the $ n $ -th point is — $ x_{n} $ . Now Yaroslav wants to execute $ m $ queries, each of them is of one of the two following types: 1. Move the $ p_{j} $ -th point from position $ x_{pj} $ to position $ x_{pj}+d_{j} $ . At that, it is guaranteed that after executing such query all coordinates of the points will be distinct. 2. Count the sum of distances between all pairs of points that lie on the segment $ [l_{j},r_{j}] $ $ (l_{j}<=r_{j}) $ . In other words, you should count the sum of: ![](https://cdn.luogu.com.cn/upload/vjudge_pic/CF295E/38769b41287eaecf62f3c386e08a6ca65538ebf0.png). Help Yaroslav.

输入输出格式

输入格式


The first line contains integer $ n $ — the number of points $ (1<=n<=10^{5}) $ . The second line contains distinct integers $ x_{1},x_{2},...,x_{n} $ — the coordinates of points $ (|x_{i}|<=10^{9}) $ . The third line contains integer $ m $ — the number of queries $ (1<=m<=10^{5}) $ . The next $ m $ lines contain the queries. The $ j $ -th line first contains integer $ t_{j} $ $ (1<=t_{j}<=2) $ — the query type. If $ t_{j}=1 $ , then it is followed by two integers $ p_{j} $ and $ d_{j} $ $ (1<=p_{j}<=n,|d_{j}|<=1000) $ . If $ t_{j}=2 $ , then it is followed by two integers $ l_{j} $ and $ r_{j} $ $ (-10^{9}<=l_{j}<=r_{j}<=10^{9}) $ . It is guaranteed that at any moment all the points have distinct coordinates.

输出格式


For each type 2 query print the answer on a single line. Print the answers in the order, in which the queries follow in the input. Please, do not use the %lld specifier to read or write 64-bit integers in C++. It is preferred to use the cin, cout streams of the %I64d specifier.
