Machine Programming Assignment for Cloud Application Course

Instructions (from PDF):

1. Divide each sentence into a list of words provided in the "delimiters" variable
2. Make all the tokens lowercase and remove any tailing and leading spaces
3. Ignore all common words provided in the "stopWordsArray" variable
4. Keep track of word frequencies
5. Sort the list by frequency in a descending order. If two words have the same number count, use the lexigraphy. For example, the following is a sorted list:

• ({Orange, 3), (Apple, 2), (Banana, 2)}

6. Return the top 20 items from the sorted list as a String Array

Note:

To make the application more interesting, you have to process only the titles with certain indexes. These indexes are accessible using the “getIndexes” method, which returns an Integer Array with 0-based indexes to the input file. It is possible to have an index appear several times. In this case, just process the index multiple times.
