Plus MinusEasy
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 6 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
\(arr = [1, 1, 0, -1, -1]\)
There are \(n = 5\) elements: two positive, two negative and one zero. Their ratios are \(\frac{2}{5} = 0.400000\), \(\frac{2}{5} = 0.400000\) and \(\frac{1}{5} = 0.200000\). Results are printed as:
0.400000 0.400000 0.200000
