Problem Description

We call a sequence $A$ of length $n$ "furry" if and only if $\forall i\in[1,n),|A_i-A_{i+1}|=1$.

We call two sequences $A,B$ of equal length $t$ to be $k$-"yrruf" only when they satisfiy two rules below.

• both $A$ and $B$ are "furry";
• $\forall i\in[1,t],|A_i-B_i|=k$.

Now you are given a sequence $A$ of length $n$ with $A_i=i$.Obviously this sequence is "furry".

There are two kinds of operations:

1. update: Given two parameters $l,r$. For each $i\in[l,r]$, if $A_i-A_{i-1}=-1$，then $\forall j\in[i,n],A_j+2\to A_j$, otherwise $\forall j\in[i,n],A_j-2\to A_j$。Obviously $A$ remained "furry" after a update.

2. query: Given three parameters $l,r,k$, ask how many sequences of length $r-l+1$ are $k$-"yrruf" with the subarray $[l,r]$ of $A$.

Please answer all the questions online.

Input Format

The first line contains two positive integers $n,m$, indicating there are $m$ operations.

The next $m$ lines each first contain an integer $o \in \{0,1\}$.

Specifically, define $lastans$ as the answer of the previous query operation.For both types of operations, the initial value of $lastans$ is $0$.

• If $o=0$, then two integers $l',r'$ follow, indicating a update with parameters $l=(l'+lastans)\bmod n+2,r=(r'+lastans)\bmod n+2$.

• If $o=1$, then three integers $l',r',k$ follow, indicating a query with parameters $l=(l'+lastans)\bmod n+1,r=(r'+lastans)\bmod n+1,k$.

Output Format

For each query, output a single integer on a separate line, representing the answer modulo $19990721$.

Hint

The first query is shown in the figure:

The second query is shown in the figure:

The third query is shown in the figure:

For all test data,it is guaranteed that $1\le n\le10^{12},m\le2\times10^5,o\in\{0,1\},0\le l^\prime,r^\prime\le10^{12}$.

• For $o=0$, it is guaranteed that $1<l\le r\le n$.
• For $o=1$, it is guaranteed that $1\le l\le r\le n,0\le k\le10^9$.

Special property: It is guaranteed that all queries occur after all updates.
