#14735. 《A theory of consciousness from a theoretical computer scienceperspective: Insights from the Conscious Turing Machine》阅读报告(更新中...)

统计

给定一个长度 $n$ 的序列 $a_1,\dots,a_n$,需要进行 $m$ 次操作,操作共有三种类型:

操作 1:给定 $l,r,x$,先新建一个数组 $b$ 满足 $b_i=a_i$,之后将 $a_x,\dots,a_{x+r-l}$ 同时修改为 $b_l,\dots,b_r$;

操作 2:给定 $l,r$,将 $a_l,\dots,a_r$ 同时修改为除以 $2$ 下取整后的值;

操作 3:给定 $l,r$,求 $a_l,\dots,a_r$ 的和。

输入格式

第一行一个整数 $n$。

接下来一行 $n$ 个整数表示序列 $a_1,\dots,a_n$。

接下来一行一个整数 $m$。

接下来 $m$ 行,每行表示一个操作:

1 l r x 表示操作 1;

2 l r 表示操作 2;

3 l r 表示操作 3。

输出格式

对每个操作 3,输出一行,包含一个整数,表示答案。

子任务

对于 $100\%$ 的数据,满足 $1\le n\le 3\cdot 10^6$,$1\le m\le 3\cdot 10^6$。

序列的初值满足 $1\le a_i\le 10^9。$

对每个操作满足 $1\le l\le r\le n$。

对每个操作 1 满足 $1\le x\le x+r-l+1\le n$。

以上所有数值为整数。
