Problem Statement

In some other world, today is the day before Christmas Eve.

Mr. Takaha is buying N items at a department store. The regular price of the i-th item (1 \leq i \leq N) is p_i yen (the currency of Japan).

He has a discount coupon, and can buy one item with the highest price for half the regular price. The remaining N-1 items cost their regular prices. What is the total amount he will pay?

Constraints

2 \leq N \leq 10

100 \leq p_i \leq 10000

p_i is an even number.

Input

Input is given from Standard Input in the following format:

N
p_1
p_2
:
p_N

Output

Print the total amount Mr. Takaha will pay.

Sample Input 1

3
4980
7980
6980

Sample Output 1

15950

The 7980-yen item gets the discount and the total is 4980 + 7980 / 2 + 6980 = 15950 yen.

Note that outputs such as 15950.0 will be judged as Wrong Answer.

Sample Input 2

4
4320
4320
4320
4320

Sample Output 2

15120

Only one of the four items gets the discount and the total is 4320 / 2 + 4320 + 4320 + 4320 = 15120 yen.

Solution in C# (Mono 4.6.2.0) (judge verdict: Accepted)

using System;
using System.Collections.Generic;

namespace ConsoleApplication1
{

    class Program
    {

        static void Main(string[] args)
        {
            int n = int.Parse(Console.ReadLine());

            int[] p = new int[n];
            int max = -1;
            int maxind = 1;

            for(int i = 0; i < n; i++)
            {
                p[i] = int.Parse(Console.ReadLine());
                if(max < p[i])
                {
                    max = p[i];
                    maxind = i;
                }
            }

            int sum = 0;
            
            for(int i = 0; i < n; i++)
            {
                if(i == maxind)
                {
                    sum += p[i] / 2;
                }
                else
                {
                    sum += p[i];
                }

            }

            Console.WriteLine(sum);

        }
