Declare variable scoreAndGrade as a HashMap with Character key type and Double value type, representing a grade and the minimum score of the grade. Read integer numData from input. Then read numData key$-$value pairs from input and insert each into scoreAndGrade. If the key already exists, do not replace the key's existing value with the new value.

Ex: If the input is:

$3$ B $80\mathrm{.}0$ C $69\mathrm{.}5$ C $70\mathrm{.}5$

then one possible output is:

Key: C$,$ Value: $69\mathrm{.}5$ Key: B$,$ Value: $80\mathrm{.}0$

Note: The order of the keys is not guaranteed in a HashMap.
