Problem Scenario 55 : You have been given below code snippet.

val pairRDDI = sc.parallelize(List( ("cat",2), ("cat", 5), ("book", 4),("cat", 12))) val pairRDD2 = sc.parallelize(List( ("cat",2), ("cup", 5), ("mouse", 4),("cat", 12)))

operation1

Write a correct code snippet for operationl which will produce desired output, shown below.

Array[(String, (Option[lnt], Option[lnt]))] = Array((book,(Some(4},None)), (mouse,(None,Some(4))), (cup,(None,Some(5))), (cat,(Some(2),Some(2)), (cat,(Some(2),Some(12))), (cat,(Some(5),Some(2))), (cat,(Some(5),Some(12))), (cat,(Some(12),Some(2))), (cat,(Some(12),Some(12)))J

Problem Scenario 59 : You have been given below code snippet.
