// 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  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



// Output Format

// Print the following  lines, each to  decimals:

// proportion of positive values
// proportion of negative values
// proportion of zeros
// Sample Input
