input: Write a function to calculate the compound interest based on the given investment amount, rate of interest, and time. The function should return the computed 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) == 1276.2815625
  assert compoundInterest(2000, 3, 4) == 2251.017
  assert compoundInterest(5000, 7, 7) == 8024.37042
output: def compoundInterest(investment_amount, rate_of_interest, time):
      compound_interest = investment_amount * (pow((1 + rate_of_interest / 100), time))
      return compound_interest
