Description

Input

The first line of the input contains an integer $t$ ($1 \leq t \leq 1000$) — the number of testcases.

The first line of each test case contains two integers $n$ and $q$ ($1 \le n, q \le 2 \cdot 10^5$) — the size of the array and the number of queries, respectively.

The second line of each test case contains $n$ integers $a_1, a_2, \dots, a_n$ ($1 \le a_i \le 10^9$).

The next $q$ lines of each test case are of two forms:

• $1$ $l$ $r$ ($1 \leq l \leq r \leq n$) — it means, for each index $i$ with $l \leq i \leq r$, you should update the value of $a_i$ to the sum of its digits.
• $2$ $x$ ($1 \leq x \leq n$) — it means you should output $a_x$.

There is at least one query of the second type.

The sum of $n$ over all test cases does not exceed $2 \cdot 10^5$.

The sum of $q$ over all test cases does not exceed $2 \cdot 10^5$.

Output

For each test case, output the answers of queries of the second type, in the order they are given.

Note

In the first test case, the following process occurs:

• Initially, $a = [1, 420, 69, 1434, 2023]$.
• The operation is performed for $l=2$, $r=3$, yielding $[1, \color{red}{6}, \color{red}{15}, 1434, 2023]$.
• We are queried for $x=2$, $x=3$, and $x=4$, and output $6$, $15$, and $1434$.
• The operation is performed for $l=2$, $r=5$, yielding $[1, \color{red}{6}, \color{red}{6}, \color{red}{12}, \color{red}{7}]$.
• We are queried for $x=1$, $x=3$, and $x=5$, and output $1$, $6$, and $7$.
