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<bits/stdc++.h>
using namespace std;
#define ll long long
const ll mxn=2e5+5;

int main() {
	ll n;
	cin>>n;
	ll a[n],i;
	unordered_map<ll,ll> mp;
	ll s=0;
	for(i=0;i<n;i++) {
		cin>>a[i];
		mp[a[i]]++;
		s+=a[i];
	}
	ll q;
	cin>>q;
	while(q--) {
		ll b,c;
		cin>>b>>c;
		s+= (c*mp[b]);
		s-= (b*mp[b]);
		mp[c]+=mp[b];
		mp[b]=0;
		cout<<s<<"\n";
	}
	return 0;
