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 CPP):

Solution:
#include <iostream>

using namespace std;


int main(){
	int n;
	int q,b,c;
	long long ans = 0;
	long long num[100010] = {0};

	cin >> n;
	for(int i = 1; i <= n; i++){
		long long a;
		cin >> a;
		ans += a;
		num[a]++;
	}	

	cin >> q;
	for(int i = 0; i < q; i++){
		cin >> b >> c;
		ans += (c - b) * num[b];
		num[c] += num[b];
		num[b] = 0;
		cout << ans << endl;	
	}
}
