Go thru each expression below and change atleast one element to test it out. SEE Scala cookbook, Look up each expression & read the description and example(s) Using Scala, starter set: List, Vectors, Double, Int, String val vec1: List[Double] = Vector(1.0, 2, 3). // best for general purpose work where random access is needed val list:List[Double] = List( 1.0, 2, 3)// good for small lists val tuple:Tuple[Double, Int, String] = (1.0, 3.0, "bongo") // can hold different types Basic tools and template for their use map, filter, fold // higher order functions that take a function as an argument and result in a list or vector, depending on what you started with zip. //merges together two lists/vectors val pairs = vec1.zip(Vector(1.0,2,3)).Use Data Bricks.
