The task was to implement two features:

1. Calculate the total number of times each word has been tweeted.

2. Calculate the median number of unique words per tweet, and update this median as tweets come in.

For this coding challenge, I write two simple programs in order to implement these two features.

Both programs are placed in a directory named src. The first program words_tweeted.py outputs the results of first feature to a text file named ft1.txt in a directory named tweet_output.

The second program median_unique.py outputs the results of first feature to a text file named ft2.txt in a directory named tweet_output.

Both programs take input tweet file named tweets.txt from a directory named tweet_input. A shell script named run.sh is also given in the main directory, that compiles and runs the programs.

My solution does require two libraries from the python standard library:

1. sys

2. collections
