input: Write a function to calculate the compound interest for a given investment amount, rate of interest, and time. If the investment amount, rate of interest, or time is zero or negative, return 0. Otherwise, return the calculated compound interest.
  
  def compoundInterest(investment_amount, rate_of_interest, time):
      if investment_amount <= 0 or rate_of_interest <= 0 or time <= 0:
          return 0
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
