Problem Scenario 67 : You have been given below code snippet.

lines = sc.parallelize(['lts fun to have fun,','but you have to know how.'])

M = lines.map( lambda x: x.replace(',7 ').replace('.',' 'J.replaceC-V ').lower())

r2 = r1.flatMap(lambda x: x.split())

r3 = r2.map(lambda x: (x, 1))

operation1

r5 = r4.map(lambda x:(x[1],x[0]))

r6 = r5.sortByKey(ascending=False)

r6.take(20)

Write a correct code snippet for operationl which will produce desired output, shown below. [(2, 'fun'), (2, 'to'), (2, 'have'), (1, its'), (1, 'know1), (1, 'how1), (1, 'you'), (1, 'but')]
