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.

import java.util.Scanner;
public class Main {
	public static void main(String[] args){
		Scanner sc = new Scanner(System.in);
		
        int N = sc.nextInt(); 
        int goodsPrices[] = new int[N];
        
        for (int i = 0; i < N; i++) {
        	goodsPrices[i] = sc.nextInt();
        }
        
        int maxPrice = goodsPrices[0];
        int totalPrice = 0;
        
        for (int i = 1; i < N; i++) {
        	if (goodsPrices[i] > maxPrice) {
        		maxPrice = goodsPrices[i];
        	}
        	
        	totalPrice += goodsPrices[i];
        }
        
        System.out.println(totalPrice - (maxPrice / 2));
		
	}
