input: Write a function to calculate the compound interest given the principal investment amount, rate of interest, and time period. Return the computed compound interest.
  
  def compoundInterest(investment_amount, rate_of_interest, time):
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
  
  assert compoundInterest(1000, 5, 5) == 1276.2815625000003
  assert compoundInterest(5000, 3, 7) == 6152.293563340012
  assert compoundInterest(200, 2, 10) == 243.80406430394323
  assert compoundInterest(1500, 4, 6) == 1938.7403519922
  assert compoundInterest(2000, 0, 3) == 2000.0
output: def compoundInterest(investment_amount, rate_of_interest, time):
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
