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>
#define ll long long 
using namespace std;
int main()
{
ll sum = 0 ;     ll n,k;
 cin>>n;
vector<int> v(n);
unordered_map<int,int> u;
for(int i = 0 ; i<n ; i++) cin>>v[i],u[v[i]]++; 
for(int i = 0 ;i<n ;i++) sum+=v[i];
cin>>k;
while(k--)
{
int a,b;
cin>>a>>b;
int cnt = u[a];
u[a]=0;
u[b]+=cnt;
sum+=(-cnt*a+b*cnt);
cout<<sum<<endl;
}
