Assume that you are developing a stock trading system . Yours ystem must keep traders of stocks in a know when there is a change on any stock.

For each stock (subject) add traders (observers), make a change such as sell or buy. Print that the person has made a change on the stock. For example, Ahmad sold jawwal stock at 100 NIS price.
