As we know, Rikka is poor at math. Yuta is worrying about this situation, so he gives Rikka some math tasks to practice. There is one of them:
Yuta has an array $A$ with $n$ numbers and he keeps a copy of the initial value of array $A$ as $A’(A_i’=A_i)$. Then he makes $m$ operations on it.
There are three types of operations:
1 l r: Yuta wants Rikka to sum up $A_i$ for all $i$ in $[l,r]$.
2 l r k: Yuta runs the C++ code
for (int i=l;i<=r;i++) A[i]=A[i-k]on sequence $A$. (The pascal version of the code snippet is
for i:=l to r do A[i]:=A[i-k]).
3 l r: Yuta changes $A_i$ back to $A_i’$, for all $i \in [l,r]$.
It is too difficult for Rikka. Can you help her?
The first line contains two numbers $1 \leq n,m \leq 2 \times 10^5$.
The second line contains $n$ numbers $A_i$. Then $m$ lines follow, each line describe an operation.
It is guaranteed that $1 \leq k \lt l,0 \leq Ai \leq 10^9$
For each query, print a single line with a single number – the answer.
