Machine Programming Assignment for Cloud Application Course
- Divide each sentence into a list of words provided in the "delimiters" variable
- Make all the tokens lowercase and remove any tailing and leading spaces
- Ignore all common words provided in the "stopWordsArray" variable
- Keep track of word frequencies
- 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)}
- 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.
