    !/bin/python3

    import math import os import random import re import sys

    #

    Complete the 'plusMinus' function below.

    #

    The function accepts INTEGER_ARRAY arr as parameter.

    #

    def plusMinus(arr): pos_num = 0 neg_num = 0 zero_num = 0

    iterate over array

    for num in arr:
    if num > 0:
        pos_num += 1
    elif num < 0:
        neg_num += 1
    else:
        zero_num += 1

    Calculate totals

    total = len(arr)
pos_ratio = pos_num/total
neg_ratio = neg_num/total
zero_ratio = zero_num/total

    Print totals

    print("{:.6f}".format(pos_ratio))   
print("{:.6f}".format(neg_ratio))
print("{:.6f}".format(zero_ratio))

    if name == 'main': n = int(input().strip())

    arr = list(map(int, input().rstrip().split()))

plusMinus(arr)

    This is the Java code

    public static void plusMinus(List arr) { // Write your code here int len=arr.size(); float posCount=0; float negCount=0; float zeroCount=0; for(int i = 0; i < len ; i++) { int elements = arr.get(i); if(elements>0){ posCount++; } else if(elements<0){ negCount++; } else{ zeroCount++; } } System.out.printf("%.6f%n",posCount/len); System.out.printf("%.6f%n",negCount/len); System.out.printf("%.6f%n",zeroCount/len); 

    }

    }
