题目描述

In mathematical terms, the sequence $F_{n}$ of Fibonacci numbers is defined by the recurrence relation

$F_{1}=1; F_{2}=1; F_{n}=F_{n-1}+F_{n-2} (n>2).$ DZY loves Fibonacci numbers very much. Today DZY gives you an array consisting of $n$ integers: $a_{1},a_{2},...,a_{n}$ . Moreover, there are $m$ queries, each query has one of the two types:

1. Format of the query " $1\ l\ r$ ". In reply to the query, you need to add $F_{i-l+1}$ to each element $a_{i}$ , where $l<=i<=r$ .
2. Format of the query " $2\ l\ r$ ". In reply to the query you should output the value of ![](/uploads/acgo/image/0539c7572cd975f6_e80be5436fba.jpeg) modulo $1000000009 (10^{9}+9)$ .

Help DZY reply to all the queries.

输入格式

The first line of the input contains two integers $n$ and $m$ ( $1<=n,m<=300000$ ). The second line contains $n$ integers $a_{1},a_{2},...,a_{n} (1<=a_{i}<=10^{9})$ — initial array $a$ .

Then, $m$ lines follow. A single line describes a single query in the format given in the statement. It is guaranteed that for each query inequality $1<=l<=r<=n$ holds.

输出格式

For each query of the second type, print the value of the sum on a single line.
