Consider a file that contains student grades such as the following:

$\backslash$table$[[$Jane Lee,$100],[$Aaron X$.$ Schmidt,$37],[$Frank von Tardy,$2]]$

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.
