Problem Statement

A country has $N$ cities and $M$ power plants, which we collectively call places. The places are numbered $1,2,\dots,N+M$, among which Places $1,2,\dots,N$ are the cities and Places $N+1,N+2,\dots,N+M$ are the power plants.

This country has $E$ power lines. Power Line $i$ ($1 \le i \le E$) connects Place $U_i$ and Place $V_i$ bidirectionally. A city is said to be electrified if one can reach at least one of the power plants from the city using some power lines.

Now, $Q$ events will happen. In the $i$-th ($1 \le i \le Q$) event, Power Line $X_i$ breaks, making it unusable. Once a power line breaks, it remains broken in the succeeding events.

Find the number of electrified cities right after each events.

Constraints

• All values in input are integers.
• $1 \le N,M$
• $N+M \le 2 \times 10^5$
• $1 \le Q \le E \le 5 \times 10^5$
• $1 \le U_i < V_i \le N+M$
• If $i \neq j$, then $U_i \neq U_j$ or $V_i \neq V_j$.
• $1 \le X_i \le E$
• $X_i$ are distinct.

Input

Input is given from Standard Input in the following format:

$N$ $M$ $E$

$U_1$ $V_1$

$U_2$ $V_2$

$\vdots$

$U_E$ $V_E$

$Q$

$X_1$

$X_2$

$\vdots$

$X_Q$

Output

Print $Q$ lines. The $i$-th line should contain the number of electrified cities right after the $i$-th event.

Initially, all cities are electrified.

• The $1$-st event breaks Power Line $3$ that connects Point $5$ and Point $10$.- Now City $5$ is no longer electrified, while $4$ cities remain electrified.
• The $2$-nd event breaks Power Line $5$ that connects Point $2$ and Point $9$.
• The $3$-rd event breaks Power Line $8$ that connects Point $3$ and Point $6$.- Now Cities $2$ and $3$ are no longer electrified, while $2$ cities remain electrified.
• The $4$-th event breaks Power Line $10$ that connects Point $1$ and Point $8$.
• The $5$-th event breaks Power Line $2$ that connects Point $4$ and Point $10$.
• The $6$-th event breaks Power Line $7$ that connects Point $1$ and Point $7$.- Now City $1$ is no longer electrified, while $1$ city remains electrified.
