题目描述

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.
