Whenever you mail a letter, you must decide how much postage to put on the envelope. You like to use this rule of thumb—use one stamp for every five sheets of paper or fraction thereof. For example, if you have 11 sheets of paper, then you use three stamps. To save money, you simply don’t mail the letter if an envelope requires more than three stamps. Given that the number of sheets is stored in a variable named numSheets, write a code fragment that prompts the user and inputs the number of sheets, calculates the number of stamps required, and prints “Use stamps” or “Don’t mail,” where is an appropriate integer value.
