Question: from operator import add lines = sc.textFile('README.md') counts = lines.flatMap(lambda x: x.split()) .map(lambda x: (x, 1)) .reduceByKey(add) The following piece of code computes

from operator import add lines = sc.textFile('README.md') counts = lines.flatMap(lambda x: x.split()) \ .map(lambda x: (x, 1)) \ .reduceByKey(add) The following piece of code computes the frequencies of the words in a text file: from operator import add lines = sc. text File ( ' README . md ' ) counts = lines.flatMap(1ambda x: x.split ( )) \ map (1ambda x: (x, 1)) .reduceByKey (add) Add one line to find the most frequent word. Output this word and its frequency Hint: Use sortBy0, reduce), or max0
