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 (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>

int setmax(int*,int);

int main(void){
    int n;
    scanf("%d",&n);
    
    int i;
    int priceset[n];
    for(i=0;i<n;i++){
        scanf("%d",&priceset[i]);
    }
    
    int ans=0;
    int m = setmax(priceset,n);
    for(i=0;i<n;i++){
        if(priceset[i]==m){
            ans += m/2;
        }else{
            ans += priceset[i];
        }
    }
    printf("%d\n",ans);
}


int setmax(int data[],int n){
    int a = 114514;
    for(int i=0;i<n;i++){
        if(data[i]<a){
            a = data[i];
        }
    }
    return a;
}
