mathCeil.js ( Math.ceil method is introduced)

 /**

* Emergency cess

Due to a natural disaster, the government is exploring various ways to gather relief fund. One proposal is to collect a one time cess from salaried employees. As per the proposal, everyone should pay ceil(7% of their monthly salary).

Given a the number of employees and their monthly salaries, help the government find the fund that can be gathered in a month.

Write a function to do this calculation.

Input

First line contains an integer n, denoting the number of employees. Next line contains n space seperated integers, denoting the monthly salaries of the n employees.

Output

One Integer, denoting the result.

Example

Sample Input:

5

100 200 300 400 555

Sample Output:

109

Explanation

First line is 5, which denotes the length of input n.

100 200 300 400 555 denotes the monthly salaries of these n people.

As per the rule,

ceil(7% of 1st person monthly salary) is 7

ceil(7% of 2nd person monthly salary) is 14

ceil(7% of 3rd person monthly salary) is 21

ceil(7% of 4th person monthly salary) is 28

ceil(7% of 5th person monthly salary) is 39

Resultant sum will be 7+14+21+28+39 = 109
