Tell us what’s happening:

I can’t understand what is being asked in the 3 and 4. And I don’t understand whats wrong with the rest?

Your code so far

How does this dictionary constructor differ from the one you created in deposit?

Here are some debugging steps you can follow. Focus on one test at a time:

  1. Are there any errors or messages in the console?
  2. What is the requirement of the failing test?
  3. Check the related User Story and ensure it’s followed precisely.
  4. What line of code implements this?
  5. What is the result of the code and does it match the requirement? (Write the value of a variable to the console at that point in the code if needed.)

If this does not help you solve the problem, please reply with answers to these questions.
