/*
 * Problem Statement: 
 * You're given an array containing integer values. You need to print the
 * fraction of count of positive numbers, negative numbers and zeroes to the
 * total numbers. Print the value of the fractions correct to 3 decimal places.
 * 
 * Input Format: 
 * First line contains N, which is the size of the array.
 * Next line contains N integers A1,A2,A3,...,AN, separated by space.
 * 
 * Constraints:
 * 1 <= N <= 100
 * -100 <= Ai <= 100
 * 
 * Output Format: 
 * Output three values on different lines equal to the fraction of count of
 * positive numbers, negative numbers and zeroes to the total numbers
 * respectively correct to 3 decimal places.
 * 
 * Sample Input:
 * 6
 * -4 3 -9 0 4 1
 * 
 * Sample Output:
 * 0.500
 * 0.333
 * 0.167
