What is the tightest Big-O running time to calculate the Flesch readability score the first time in the EfficientDocument class, where n is the length of the document, assuming you include the time it takes to initialize the numSyllables, numWords, and numSentences variables?

Note that this is not necessarily the running time that you saw when you plotted the graph of your EfficientDocument running time when you did your benchmarking. That time included the time to initialize the numSyllables, numWords and numSentences variables.
