Advanced Topics 13. Average Load Time Calculator

// We have a report that holds dates, web site URLs and load times (in seconds) in the same format like in the examples below. Your tasks is to calculate the average load time for each URL. Print the URLs in the same order as they first appear in the input report. Use double floating-point precision.
