Perform the following steps in a single code cell.

$1.$ Create a function named process$\_$row$().$ This function should accept a single parameter named row, which is intended to represent individual elements of the nasa$\_$raw RDD$.$ The function should perform the follow processing tasks on the string contained in row, in the order described.

a$.$ Use the string replace$()$ method to replace double quotes with empty strings.

b$.$ Tokenize the string on space characters using the split$()$ method.

c$.$ If the last token $($indicating bytes$)$ is equal to a hyphen, replace it with $0.$

d$.$ Coerce the bytes token to an integer. $($Note that the status code could be interpreted as an integer, but we will leave it as a string to more easily reflect that this is categorical information$).$

e$.$ Return the resulting list of tokens.

$2.$ Apply the process$\_$row$()$ function to the elements of nasa$\_$raw to create a new RDD named nasa. The new RDD should contain the same number of elements as nasa$\_$raw, but these elements should be lists instead of strings.

$3.$ Persist the nasa RDD to memory.

$4.$ Print the first $10$ elements of the nasa RDD$,$ with each element appearing on a different line of

output.
