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:
import java.util.*;

public class Main {
    public static void main(String[] args) throws Exception {
        // Your code here!
        Scanner sc = new Scanner(System.in);
        int n = sc.nextInt();
        TreeMap<Integer, Integer> map = new TreeMap<Integer, Integer>();
        long sum = 0;
        for (int i = 0; i < n; i++) {
            int num = sc.nextInt();
            int val = map.getOrDefault(num, 0);
            map.put(num, ++val);
            sum = sum + num;
        }
        
        int q = sc.nextInt();
        while (q-- > 0) {
            int prev = sc.nextInt();
            int next = sc.nextInt();
            
            long dif = next - prev;
            
            int prevcount = map.getOrDefault(prev, 0);
            sum = sum + dif * prevcount;
            
            map.remove(prev);
            int val = map.getOrDefault(next, 0);
            map.put(next, val + prevcount);
            System.out.println(sum);
