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

Ex: If the input is:

$3$ Ron $84\mathrm{.}5$ Kim $79\mathrm{.}0$ Kim $88\mathrm{.}0$

then one possible output is:

Key: Ron, Value: $84\mathrm{.}5$ Key: Kim, Value: $79\mathrm{.}0$
