#

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);

}

}

foreach(int number in arr) { if (number>0) {
positives+=1; } else if (number<0) { negatives+=1; } else { zeros+=1; }
} System.Console.WriteLine("{(negatives/arr.Count):F6}"); System.Console.WriteLine($"{(zeros/arr.Count):F6}");
