whenever I post these questions I get some random reply please just help with answering the questions.

1. Which functions did you use a nested structure (nested loops, nested conditionals, etc) to implement the requirements? Would it have been possible to implement them without using a nested structure? Which functions did you not use a nested structure? Would it have been possible to implement them with a nested structure? 2. Suppose we wanted to create an additional map classification called 'Urban City' which is indicated by the number of 'R' cells plus the number of 'C' cells being between 60% and 80%. Can we do this? How might this affect our classify_map() function? 3. How many test cases would you need to confirm that your classify_map() function correctly identifies a "Farmland" map? Explain what your test cases would be
