input: Write a function to calculate the compound interest given the investment amount, rate of interest, and time. Return the compound interest value.
  
  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, 10) == 6719.581895381382
  assert compoundInterest(200, 7, 2) == 229.1930
output: def compoundInterest(investment_amount, rate_of_interest, time):
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
