Background

CodingBat is a free site of live problems to build skill in Java and/or Python. It was created by Nick Parlante, who is Computer Science lecturer at Stanford. The name "CodingBat" was based on the Greek word "bat" meaning "this domain was available" (or so they say).

Part 1: Account Setup

1. Go to codingbat.com and create an account (click the link on the upper right).
   Please use your JMU email when setting up your account.

2. After logging in, click the "prefs" link (upper right) and "share to" your instructor's email (mayfiecs@jmu.edu or weikleda@jmu.edu) so you will get credit.
   Also make sure your name is entered as shown: Last, First

Part 2: Problem Solving

3. Work through several of the Warmup-1 problems. All of them have solutions available; try to solve them first before looking at the answer.

4. Some of the warm up problems will require you to use String methods like charAt, equals, length, and substring. Don't worry about any problems that require for loops; we'll get to that next week.

5. Solve as many of the Logic-1 problems as you can today. At a minimum, solve the following:
   squirrelPlay, caughtSpeeding, withoutDoubles, and shareDigit.

6. Solve as many of the Logic-2 problems as you can today. At a minimum, solve the following:
   roundSum and blackjack.

7. You might find (on CodingBat's site) the Boolean Logic video 1 and video 2 useful.

You don't need to turn in anything via Canvas today. We will grade your progress directly from CodingBat, and we will use CodingBat in subsequent labs. You are encouraged to work on CodingBat problems at any time.
