Computer science often deals with extremes when it comes to time. Even though modern computers can perform billions of operations per second, some tasks—such as decoding an encrypted message— still might require decades of computation.
Create a Web page named years.html that prompts the user to enter a specific number of years and then displays the corresponding time in seconds. To simplify this task, ignore leap years and assume that all years consist of exactly 365 days. For example, given an input value of 2.5, your page should display the message: That’s 78840000 seconds! Once you complete your page, use it to approximate the number of seconds left in the current school semester. How many seconds remain in your college career? Report your results.
