Temperatures

Codingame: Temperatures
Original Problem

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

Java Solution

class Solution {

        public static void main(String args[]) {
            Scanner in = new Scanner(System.in);
            int n = in.nextInt(); // the number of temperatures to analyse
            if (in.hasNextLine()) {
                in.nextLine();
            }
            String temps = in.nextLine(); // the n temperatures expressed as integers ranging from -273 to 5526       
            int minForPositives = 5526;
            int maxForNegatives = -273;
            int result = 0;
            String[] tempsStr = new String[n];
            tempsStr = temps.split(" ");
            int[] numbers = new int[n];

            for (int i = 0; i < n; i++) {
                numbers[i] = Integer.parseInt(tempsStr[i]);
            }

            for (int i = 0; i < n; i++) {
                if (numbers[i] < 0 && maxForNegatives < numbers[i]) maxForNegatives = numbers[i];
                if (numbers[i] > 0 && minForPositives > numbers[i]) minForPositives = numbers[i];
            }

            if (Math.abs(maxForNegatives) >= minForPositives) {
                result = minForPositives;
            }
            if (Math.abs(maxForNegatives) < minForPositives) {
                result = maxForNegatives;
            }
            if (n == 0) {
                result = 0;
            }
            if (n == 1 && numbers[0] == 5526) {
                result = 5526;
            }
            System.out.println(result);
        }
    }
