Hints

1. Translate a numeric grade to a letter grade

• Use an if-then-else expression with as many elif branches as needed.

2. Count the number of students for each letter grade

• The reduce filter needs a stream to iterate over. The input is an object. Use the to_entries expression to transform the object into an array.
• The result object must have all the possible letter grades as keys, even if no students earned that grade.
• The += assignment will be useful.
