input: Write a function to calculate the compound interest given the investment amount, rate of interest, and time in years. The function should return the compound interest value. If the input values are invalid (e.g., negative values), return 0.
  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
  
  assert compoundInterest(1000, 5, 5) == 1276.2815625
  assert compoundInterest(500, 3, 10) == 671.9581875
  assert compoundInterest(2000, 7, 15) == 5530.6068875
  assert compoundInterest(-100, 5, 5) == 0
  assert compoundInterest(1000, -5, 5) == 0
  assert compoundInterest(1000, 5, -5) == 0
output: def compoundInterest(investment_amount, rate_of_interest, time):

          return 0
