// An imaginary magical school has a new report card generation system written in rust!
|
|
// Currently the system only supports creating report cards where the student's grade
|
|
// is represented numerically (e.g. 1.0 -> 5.5). However, the school also issues alphabetical grades
|
|
// (A+ -> F-) and needs to be able to print both types of report card!
|
|
|
|
// Make the necessary code changes to support alphabetical report cards, thereby making the second
|
|
// test pass.
