collections.Counter() 

 A counter is a container that stores elements as dictionary keys, and their counts are stored as dictionary values.

 Sample Code 

>>> from collections import Counter
>>> 
>>> myList = [1,1,2,3,4,5,3,2,3,4,2,1,2,3]
>>> print Counter(myList)
Counter({2: 4, 3: 4, 1: 3, 4: 2, 5: 1})
>>>
>>> print Counter(myList).items()
[(1, 3), (2, 4), (3, 4), (4, 2), (5, 1)]
>>> 
>>> print Counter(myList).keys()
[1, 2, 3, 4, 5]
>>> 
>>> print Counter(myList).values()
[3, 4, 4, 2, 1]

Task

$\textit{Rightu}$ is a shoe shop owner. His shop has $\mbox{X}$ number of shoes. 

He has a list containing the size of each shoe he has in his shop. 

There are $N$ number of customers who are willing to pay $x_i$ amount of money only if they get the shoe of their desired size.

Your task is to compute how much money $\textit{Rightu}$ earned.

Input Format

The first line contains $\mbox{X}$, the number of shoes. 

The second line contains the space separated list of all the shoe sizes in the shop.

The third line contains $N$, the number of customers. 

The next $N$ lines contain the space separated values of the $\textit{shoe size}$ desired by the customer and $x_i$, the price of the shoe.

Constraints

$0<X<10^3$ 

$0<N\leq10^3$ 

$20<x_i<100$ 

$2<shoe size<20$

Output Format

Print the amount of money earned by $\textit{Rightu}$. 

Sample Input
10

6
6 55
6 45
6 55
4 40
18 60
10 50

Sample Output
200

Explanation

Customer 1: Purchased size 6 shoe for $55. 

Customer 2: Purchased size 6 shoe for $45. 

Customer 3: Size 6 no longer available, so no purchase. 

Customer 4: Purchased size 4 shoe for $40. 

Customer 5: Purchased size 18 shoe for $60. 

Customer 6: Size 10 not available, so no purchase.

Total money earned = $55+45+40+60=$ $\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\$
