Description

Larry graduated this year and finally has a job. He's making a lot of money, but somehow never seems to have enough. Larry has decided that he needs to grab hold of his financial portfolio and solve his financing problems. The first step is to figure out what's been going on with his money. Larry has his bank account statements and wants to see how much money he has. Help Larry by writing a program to take his closing balance from each of the past twelve months and calculate his average account balance.

Input

The input will be twelve lines. Each line will contain the closing balance of his bank account for a particular month. Each number will be positive and displayed to the penny. No dollar sign will be included.

Output

The output will be a single number, the average (mean) of the closing balances for the twelve months. It will be rounded to the nearest penny, preceded immediately by a dollar sign, and followed by the end-of-line. There will be no other spaces or characters in the output.

Sample Input

Sample Output

$1581.42

题意简述：输入１２个数，计算其平均值。

问题分析：（略）

程序说明：编写程序时，考虑到C++处理输入比较方便，所以使用C++语言编程。然而，输出需要指定格式是还是C语言方便，所以就用函数printf()来处理输出。

AC的C语言程序如下：

/* UVALive2362 POJ1004 HDU1064 ZOJ1048 Financial Management */

#include <iostream>
#include <cstdio>

using namespace std;

int main()
{
    double val, sum;

    sum = 0;
    for(int i=1; i<=12; i++) {
        cin >> val;
        sum += val;
    }

    printf("$%.2f\n", sum / 12);

    return 0;
}
