# Codingame: Temperatures

## 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).## Game Input

Your program must read the data from the standard input and write the result on the standard output.

**Input**

Line 1: `N`, the number of temperatures to analyze

Line 2: A string with the `N` temperatures expressed as integers ranging from -273 to 5526

**Output**

Display 0 (zero) if no temperatures are provided. Otherwise, display the temperature closest to 0.

**Constraints**

0 ≤

`N`< 10000## C++ Solution

#include <iostream> #include <string> #include <vector> #include <algorithm> #include <sstream> #include <iterator> using namespace std; int main() { int N; cin >> N; cin.ignore(); string TEMPS; getline(cin, TEMPS); istringstream buf(TEMPS); int tmp, min = 0; for (int i = 0; i < N; ++i) { buf >> tmp; if (i == 0 || abs(tmp) < abs(min)) { min = tmp; } else if (abs(tmp) == abs(min)) { min = abs(tmp); } } cout << min << endl; return 0; }
