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.

#include <bits/stdc++.h>
#define ll long long
#define pb push_back
#define F first
#define S second

using namespace std;
const int N = 1e5 + 5 , mod = 1e9 + 7;

int A[N];

int main()
{
    ios :: sync_with_stdio(0); cin.tie(0); cout.tie(0);
    int n , sum = 0; cin >> n;
    for (int i=0; i<n; i++)
        cin >> A[i];
    sort(A , A+n);
    for (int i=0; i<n-1; i++)
        sum += A[i];
    sum += A[n-1]/2;
    cout << sum;
