Given a graph with vertices divided into N groups, each containing $2^M$ vertices that are numbered from 0 inside the group.
Initially there is no edge. There are Q queries. Each query will be of one of the following 3 types:
$1 \space i \space j \; p$: For every vertex numbered x from 0 to $2^m-1$ add an edge between vertex x from group i and vertex $x \oplus p$ from group j.
$2 \; i \; x$: Find the size of component containing vertex x in group i.
3: Count the total number of connected components.

Input Format:
First line consists of three space separated integers denoting N, M and Q.
Q lines follow, each containing one of the given 3 types of queries.

Output Format:
For every query of type 2 and 3 print the required answer in a new line.

Constraints:
$1 \le N \le 10^5$
$1 \le M \le 40$
$1 \le Q \le 4 \times 10^5$
$0 \le p, x \le 2^M-1$
$1 \le i, j \le N$

SAMPLE INPUT
3 1 3
1 1 2 1
3
2 2 0
SAMPLE OUTPUT
4
2

Explanation

The first query connects following vertices:
Vertex 0 of group 1 to vertex 1 of group 2.
Vertex 1 of group 1 to vertex 0 of group 2.

So connected components is 4.
Size of component containing vertex 0 of group 2 is 2.
