Complete the 'plusMinus' function below.

#

The function accepts INTEGER_ARRAY arr as parameter.

# def count_positive(a): return int(a > 0) def count_negative(a): return int(a < 0) def count_zero(a): return int(a == 0)

def plusMinus(arr): # Write your code here l = len(arr) p = sum(map(count_positive, arr)) n = sum(map(count_negative, arr)) z = sum(map(count_zero, arr)) print(f"{p/l:.6f}") print(f"{n/l:.6f}") print(f"{z/l:.6f}") if name == 'main': n = int(input().strip())

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