input: Write a function to calculate the compound interest based on the given investment amount, rate of interest, and time period. 
  
  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) == 1276.2815625
  assert compoundInterest(2000, 3, 7) == 2459.723038468261
  assert compoundInterest(100, 10, 2) == 121.0
output: def compoundInterest(investment_amount, rate_of_interest, time):
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
