Problem solving for whiteboard interviews

Problem solving is a core skill for software engineers. Whether you are debugging something in a code base, or working through an interview challenge, you will need to have a plan in place for how to approach the problem. Without one, you may find yourself quickly getting stuck or distracted by unrelated issues. Worse - during an in-person interview, you might find it difficult to stay on track, focused and able to scope the problem. Having a well rehearsed process will help you come accross as confident and professional.

The problem solving process is based on mathematician George Pólya's technique read more

Most the details will be specific to whiteboarding problems, but the general technique can be used for any problem solving scenario

If this technique fails, Pólya advises "If you can't solve a problem, then there is an easier problem you can solve: find it." Or: "If you cannot solve the proposed problem

/**

  * Implement a `map` method on this Tree class, using pseudoclassical instantiation.
  *
  * Map accepts a mapping function as its only argument. It traverses the tree,
  * passing each node's value into the mapping function, and generates a new
  * tree containing the results.
  *
  * So `map` should return a tree with the same structure, and different values,
  * but it should NOT modify the tree that was passed in.

the changes should look like this, server.js:
