Cindy uses the services of a brokerage firm to buy and sell stocks. The firm charges 1.5% service charges on the total amount for each transaction -- buy or sell. When Cindy sells stocks, she would like to know if she gained or lost on a particular investment.

The program outputs the amount invested, the total service charges, amount gained or lost, and the amount received after selling the stock. Using Python
