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: Accepted)

#include "stdio.h"

int main(void){
  int N;
  if(scanf("%d", &N)==EOF)
    return 0;
  int a[N];
  int max, sum;
  for(int i=0; i <N; i++){
  	if(scanf("%d", &a[i])==EOF) return 0;
    if(a[i] >= max)
      max = a[i];
  }
  int flag =1;
  for(int i=0; i < N; i++){
    if(a[i]==max && flag ==1){
      sum += a[i] / 2;
      flag = 0;
    }
    else
      sum += a[i];
  }
  printf("%d", sum);

}
