lodgerData is a HashMap with String key type and Character value type, representing the name and room label of a guest. Integer numToRead is read from input. Then numToRead key$-$value pairs are read from input and inserted into lodgerData. Output each key in the HashMap followed by $"$; $".$

Ex: If the input is:

$2$

Taj G Noa Z

then one possible output is:

All keys found: Noa; Taj;

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