Letter Grade |2|
~~~~~~~~~~~~~~~~

| In our letter grade system, our total point obtained in a course is
  converted to a letter grade. In this question, you will write a
  program that reads the total point from the user and prints the
  corresponding letter grade.
| Total point intervals and their letter grade equivalents:
| - 90-100 :math:`\rightarrow` AA
| - 85-89 :math:`\rightarrow` BA
| - 80-84 :math:`\rightarrow` BB
| - 75-79 :math:`\rightarrow` CB
| - 70-74 :math:`\rightarrow` CC
| - 65-69 :math:`\rightarrow` DC
| - 60-64 :math:`\rightarrow` DD
| - 50-59 :math:`\rightarrow` FD
| - 0-49 :math:`\rightarrow` FF
