codingame （一）--Temperatures（base）

The Goal：

In this exercise, you have to analyze records of temperature to find the closest to zero.

Sample temperatures Here, -1 is the closest to 0.

Rules：

Write a program that prints the temperature closest to 0 among input data. If two numbers are equally close to zero, positive integer has to be considered closest to zero (for instance, if the temperatures are -5 and 5, then display 5).

我的代码：

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>

using namespace std;

/**
