Getting Started
Import CS201_Lab19.zip (File→Import...→General→Existing Projects into Workspace→Archive File). You should see a project called CS201_Lab19 in the Package Explorer.
Your Task
Implement each static method in the class called Recursion. Each method has comments describing what it should do.
When you implement a method, remove the line of code reading
throw new UnsupportedOperationException("Not implemented yet");A JUnit test class called RecursionTest contains test cases for each method.
You must use recursion in each method. Do not use a loop in any of the methods.
As you think about how to implement each method, consider:
- What is a base case (or base cases) that can be solved without using recursion?
- How can you find a subproblem which has the same form as the overall problem?
- How can you extend the solution to the subproblem to solve the overall problem?
