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: $N$ $p_1$ $p_2$ $:$ $p_N$ [samples]

Samples

Input #1

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.

Input #2

Output #2

15120

Only one of the four items gets the discount and the total is $4320 / 2 + 4320 + 4320 + 4320 = 15120$ yen.
