Integer dataSize is read from input. Then, dataSize pairs of strings and integers are read and stored into string vector furnitureList and integer vector quantityList, respectively. Lastly, integer quantityThreshold is read from input. Complete the following tasks:

Initialize firstPosition with $-1.$

Use a loop to find the first element pair with a quantity less than or equal to quantityThreshold. If the element pair is found, assign firstPosition with the index of the element pair and output the furniture and quantity, separated by a space. End with a newline.
