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 Go (1.6) (judge verdict: Accepted)

package main

import (
	"bufio"
	"fmt"
	"os"
	"strconv"
)

var sc = bufio.NewScanner(os.Stdin)

func maxScanTokenSize(size int) {
	buf := make([]byte, 0, size)
	sc.Buffer(buf, size)
}

func nextString() string {
	sc.Scan()
	return sc.Text()
}

func nextBytes() []byte {
	sc.Scan()
	return sc.Bytes()
}

func nextInt() int {
	s := nextString()
	i, _ := strconv.Atoi(s)
	return i
}

func scanTwoInts() (int, int) {
	var a, b int
	fmt.Scan(&a, &b)
	return a, b
}

func scanThreeInts() (int, int, int) {
	var a, b, c int
	fmt.Scan(&a, &b, &c)
	return a, b, c
}

func main() {
	// maxScanTokenSize(100000)
	// sc.Split(bufio.ScanWords)

	N := nextInt()

	max := 0
	ans := 0
	for i := 0; i < N; i++ {
		p := nextInt()
		ans += p
		if p > max {
			max = p
		}
	}
	ans -= max / 2
	fmt.Println(ans)
}
