Problem: You have a sequence A composed of N positive integers: A_{1}, A_{2}, \cdots, A_{N}.

You will now successively do the following Q operations:

* In the i-th operation, you replace every element whose value is B_{i} with C_{i}.



For each i (1 \leq i \leq Q), find S_{i}: the sum of all elements in A just after the i-th operation.

Constraints

* All values in input are integers.
* 1 \leq N, Q, A_{i}, B_{i}, C_{i} \leq 10^{5}
* B_{i} \neq C_{i}

Input

Input is given from Standard Input in the following format:


N
A_{1} A_{2} \cdots A_{N}
Q
B_{1} C_{1}
B_{2} C_{2}
\vdots
B_{Q} C_{Q}


Output

Print Q integers S_{i} to Standard Output in the following format:


S_{1}
S_{2}
\vdots
S_{Q}


Note that S_{i} may not fit into a 32-bit integer.

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {

	public static void main(String[] args) {

		// 読み込み
		Scanner sc = new Scanner(System.in);
		int N = sc.nextInt();
		int[] ai = new int[100001];
		
		long sum = 0;
		for (int i = 0; i < N; i++) {
			int a = sc.nextInt();
			sum += a;
			ai[a] ++;
		}

		int Q = sc.nextInt();

		for (int i = 0; i < Q; i++) {
			int b = sc.nextInt();
			int c = sc.nextInt();

			long add_or_sub = 0;
			ai[c] += ai[b];
			add_or_sub = c * ai[b] - b * ai[b];
			ai[b] = 0;
			
			sum += add_or_sub;
			System.out.println(sum);
		}
	}
