This learning exercise helped evolve your knowledge of Arrays, For-Each Loops, and For Loops.
In this exercise you will implement a partial set of utility routines to help a developer clean up SqueakyClean names. In the 4 tasks you will gradually build up the clean method. A valid SqueakyClean name is comprised of zero or more letters and underscores. In all cases the input string is guaranteed to be non-null. Note that the clean method should treat an empty string as valid.

Instructions: In this exercise you'll be playing around with a remote controlled car, which you've finally saved enough money for to buy. Cars start with full (100%) batteries. Each time you drive the car using the remote control, it covers 20 meters and drains one percent of the battery. The remote controlled car has a fancy LED display that shows two bits of information: The total distance it has driven, displayed as: "Driven <METERS> meters". The remaining battery charge, displayed as: "Battery at <PERCENTAGE>%". If the battery is at 0%, you can't drive the car anymore and the battery display will show "Battery empty". You have six tasks, each of which will work with remote controlled car instances.
Instructions: In this exercise you'll be working on an appointment scheduler for a beauty salon in New York that opened on September 15th in 2012.
Instructions: Karl wants to keep track of a list of languages to learn on Exercism's website. Karl needs to be able to add new languages, remove old ones and check if certain languages are in the list. It would be very exciting if Karl wants to learn Java or Kotlin!
