Declare variable scoreAndNotes as a HashMap with Double key type and String value type, representing a test score and a teacher's comment on the score. Read integer dataCount from input. Then read dataCount key$-$value pairs from input and insert each into scoreAndNotes. If the key already exists, do not replace the key's existing value with the new value.

Ex: If the input is:

$397\mathrm{.}5$ excellent $74\mathrm{.}0$ good $74\mathrm{.}0$ satisfactory

then one possible output is:

Key: $74\mathrm{.}0,$ Value: good Key: $97\mathrm{.}5,$ Value: excellent
