  假設您以固定的年率利儲存一筆金額於活期存款帳戶。需要存多少前才能在三年後帳戶會有$5000?
  可利用下
  列公式獲得最初的存款金額:
  
  initialDepositAmount = FINAL_ACCOUNT_VALUE / (1 + monthlyInterestRate) ** \
  numberOfMonths
  
  撰寫一程式，提示使用者輸入帳戶總額、年利率，以及年數，然後顯示最初的存款金額。以下是範例輸出樣本:
  
  ```
  Enter final account value: 1000
  Enter annual interrest rate in percent: 4.25
  Enter number of years: 5
  Initial deposit value is 808.8639197424636
  ```
  """
  
  FINAL_ACCOUNT_VALUE = int(input("Enter final account value:"))
  ANNUAL_INTEREST_RATE = int(input("Enter annual interrest rate in percent:"))
  NUMBER_OF_YEARS = int(input("Enter number of years:"))
  
  NUMBER_OF_MONTHS = NUMBER_OF_YEARS * 12
  MONTHLY_INTEREST_RATE = ANNUAL_INTEREST_RATE / 1200
  
  INITIAL_DEPOSIT_AMOUNT = FINAL_ACCOUNT_VALUE / (1 + MONTHLY_INTEREST_RATE) ** \
                                              NUMBER_OF_MONTHS
  
  print("Initial deposit value is", INITIAL_DEPOSIT_AMOUNT)
