Consider a file that contains student grades such as the following: Jane Lee Aaron X. Schmidt Frank von Tardy 100 37 2 As with the country names, the student names don't have a fixed number of words. To process the input, read one line of input at a time. Then, starting from the end of the line, keep moving toward the beginning until you no longer see digits. Then break the line up into a name and a grade. Remember to remove any spaces between the name and the grade. Not all lines are useful.

As with the country names, the student names don't have a fixed number of words. To process the input, read one line of input at a time. Then, starting from the end of the line, keep moving toward the beginning until you no longer see digits. Then break the line up into a
name and a grade. Remember to remove any spaces between the name and the grade.
Not all lines are useful.
