The 63 U.S. Nаtiоnаl Pаrks are spread acrоss 30 states and territоries. Some states are park-rich (California has 9, Alaska has 8); others draw huge crowds to a single famous park. In this problem, you will summarize visitation to the National Park system by state for a given year. Write a function named state_totals that accepts three arguments: a parks file name, a visits file name, and a year. Return a pandas Series indexed by state, where each value is the total recreation visits to all National Parks in that state during the given year, sorted from highest total to lowest. Open this problem in Vocareum to write and submit your solution. A few ground rules while you work: Keep this Canvas quiz and Honorlock open for the duration of the problem. Do not close or submit the quiz until you are finished in Vocareum. You do not need to write or submit anything in Canvas. We will check Vocareum for your solution. You may submit and test your solution in Vocareum as many times as you like before the quiz time limit expires. Once the quiz ends, Vocareum will lock and you will not be able to make further changes. The data file is available in your Vocareum workspace. You do not need to upload it. It is linked above only for your reference. For full credit, your function should use pandas concepts and techniques to calculate and return the result without using loops or list comprehensions.
