Problem Statement
You are given N, Q, and $A=(a_1,\ldots,a_N)$.
Process Q queries described below. Each query is of one of the following three kinds:
- 1 L R x: for $i=L,L+1,\dots,R,$ update the value of a_i to $\displaystyle \left\lfloor \frac{a_i}{x} \right\rfloor$.
- 2 L R y: for $i=L,L+1,\dots,R,$ update the value of a_i to y.
- 3 L R: print $\displaystyle\sum_{i=L}^R a_i$.
Input
Input is given from Standard Input in the following format, where $\text{query}_i$ denotes the i-th query to be processed:
N Q
$a_1 a_2 \dots a_N$
$\text{query}_1$
$\text{query}_2$
$\vdots$
$\text{query}_Q$
Each query is given in one of the following three formats:
1 L R x
2 L R y
3 L R
Output
Print the answer to the queries as specified in the Problem Statement, with newlines in between.
Constraints
- $1 \leq N \leq 5 \times 10^5$
- $1 \leq Q \leq 10^5$
- $1 \leq L \leq R \leq N$
- $1 \leq a_i \leq 10^5$
- $2 \leq x \leq 10^5$
- $1 \leq y \leq 10^5$
- All values in input are integers.

Initially, A = (2, 5, 6). Thus, the answer to the 1-st query is a_1 + a_2 + a_3 = 2 + 5 + 6 = 13.
When the 2-nd query has been processed, A = (2, 2, 3). Thus, the answer to the 3-rd query is a_1 + a_2 = 2 + 2 = 4.
When the 4-th query has been processed, A = (3, 3, 3). Thus, the answer to the 5-th query is a_1 + a_2 + a_3 = 3 + 3 + 3 = 9.
