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 PYTHON):

Solution:
from collections import Counter
input = raw_input
n = int(input())
As = list(map(int, input().split(" ")))
nums = [0] * (10**5+1)

counter = Counter(As)
cur_sum = sum(As)

for key, val in counter.items():
    nums[key] = val

q = int(input())
for i in range(q):
    b, c = map(int, input().split(" "))

    num1 = counter[b]
    counter[b] = 0
    counter[c] += num1

    diff = (c - b) * num1

    cur_sum += diff
    print(cur_sum)
