The function returns the distance between them as an output argument called distance. For example, the call get distance('Seattle, WA', "Miami, FL') should return 3723.

spreadsheet is shown below. The first row and first column contain the city names using the following format: city name comma space capitalized
state abbreviation, e.g, Nashville, TN. Note that the very first cell of the spresheet, A1, is blank.
Write a function called get_distance that accepts two character vector inputs representing the names of two cities. The functian returns the distance
between them as an output argument called distance. For example, the cali get_distance('Seattle, WA', Miami, FL') should return 3723. If one ar
both of the specified cities are not in the file, the function returns 1.
Your function should load the data only once. File VO is a time consuming operation. Loading the date multiple times is will likely cause a time-out
error when submitting your function.
