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++14 (GCC 5.4.1) (judge verdict: Accepted)

#include<stdio.h>

int main(void)
{
        int n, i;

        scanf("%d", &n);

        int p[n],sum=0,max;
        for(i=0; i<n; i++){
                scanf("%d", &p[i]);
                if(p[i]%2!=0) return 1;
        }

        max=p[0];
        for(i=1; i<n; i++){
                if(p[i]>max){
                        max=p[i];
                }
        }

        int flag=0;

        for(i=0; i<n; i++){
                if(flag != 1 && max==p[i]){
                        p[i]=0;
                        flag = 1;
                }
                sum  += p[i];
        }

        sum += max/2;

        printf("%d\n",sum);

        return  0;
}
