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;
//using System.Linq;
class Program
{
  //static List<string> list;
	static void Main(string[] args)
	{
		// 入力フェーズ
        int N = int.Parse(Console.ReadLine());
        int[] t = new int[N];

        for(int i=0; i<N; i++)
        {
          t[i] = int.Parse(Console.ReadLine());
        }

        // 最大値と合計値をだす
        int max = 0, sum = 0;
        for(int i=0; i<N; i++)
        {
          if(max < t[i])
            max = t[i];

          sum += t[i];
        }

        int ret = sum - max/2;
        
    // 出力
        Console.WriteLine(ret);
    }
		class myClass{ //自作クラス
			public int ID {set; get;}
			public long Point {set; get;}
		}
    static private int getMaxPoint(int solve, int[,] table)
    {
      int ret = 0;

      return ret;
    }
