Plus Minus Problem 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. public static void plusMinus(List<Integer> arr) { // Write your code here double pos=0; double neg=0; double zero=0; double n=arr.size(); for(int i:arr) { if(i>0) pos++; if(i<0) neg++; if(i==0) zero++; } Formatter fm=new Formatter(); fm.format("%.6f", pos/n); System.out.println(fm); fm=new Formatter(); fm.format("%.6f", neg/n); System.out.println(fm); fm=new Formatter(); fm.format("%.6f", zero/n); System.out.println(fm); }
