Integer numElements is read from input. Then, numElements pairs of strings and integers are read and stored into string vector subjectList and integer vector pageList, respectively. Lastly, integer pageThreshold is read from input.

Set matchCount with the number of element pairs with a page less than pageThreshold.

Output the subject of each pair found with a page less than pageThreshold. End with a newline.
