Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with places after the decimal.

Note: This challenge introduces precision problems. The test cases are scaled to six decimal places, though answers with absolute error of up to 10^-4 are acceptable.

Example

There are elements, two positive, two negative and one zero. Their ratios are , and . Results are printed as:

0.400000

0.400000

0.200000

Function Description

Complete the plusMinus function in the editor below.

plusMinus has the following parameter(s):

int arr[n]: an array of integers

Print

Print the ratios of positive, negative and zero values in the array. Each value should be printed on a separate line with digits after the decimal. The function should not return a value.

Input Format

The first line contains an integer, , the size of the array.

The second line contains space-separated integers that describe .

Constraints

0<n<=100

-100<=arr[i]<=100

Output Format

Print the following lines, each to decimals:

proportion of positive values

proportion of negative values

proportion of zeros

Sample Input

STDIN Function

6 arr[] size n = 6

-4 3 -9 0 4 1 arr = [-4, 3, -9, 0, 4, 1]

Sample Output

0.500000

0.333333

0.166667

Explanation

There are positive numbers, negative numbers, and zero in the array.

The proportions of occurrence are positive: , negative: and zeros:
