Plus Minus

FRom hackerrank

Given an array of integers, calculate the fractions of its elements that are positive, negative, and are zeros. Print the decimal value of each fraction on a new line.


Solution in C# -


class Solution {

    static void plusMinus(int[] arr) {

        float len = arr.Length;
        int positive = 0, negative = 0, zero = 0;
        foreach(int a in arr)
        {
            if(a > 0)
            positive++;
            else if(a < 0)
            negative++;
            else
            zero++;
        }
        Console.WriteLine(positive/len);
        Console.WriteLine(negative/len);
        Console.WriteLine(zero/len);
    }

    static void Main(string[] args) {
        int n = Convert.ToInt32(Console.ReadLine());

        int[] arr = Array.ConvertAll(Console.ReadLine().Split(' '), arrTemp => Convert.ToInt32(arrTemp));
        plusMinus(arr);
    }
