Code Challenge 1

This is the answer for the string compression and uri comparison.

How to run the source code

First question:

$ node compress.js

I have 5 unit test cases: One from zendesk question, another longer string, two very simple strings, and two edge cases (which return empty strings). The output of the strings should be as follows:

Input:  aaaabbaaaababbbcccccccccccc
Return:  a4b2a4b1a1b3c12


Input:  aaaaaaaaaaaaalllllllldddfffeeeeeeeebbbbbbbbeggggggggabbaaaababbbccccccccccccccccccccccccccc
Return:  a13l8d3f3e8b8e1g8a1b2a4b1a1b3c27


Input:  a
Return:  a1


Input:  abc
Return:  a1b1c1


Input:  undefined
Return:


Input:
Return:

..

Second Question:

$ node uriComparison.js

Similarly I have 7 unit test cases. The result is:

http://abc.com:80/~smith/home.html
http://ABC.com/%7Esmith/home.html
true


http://abc.com/drill/down/foo.html
http://abc.com/drill/further/../down/./foo.html
true


http://abc.com/drill/down/foo.html
http://abc.com/drill/further/../../drill/down/./foo.html
true


http://abc.com/foo.html?a=1&b=2
http://abc.com/foo.html?b=2&a=1
true


http://abc.com/foo.html?a=1&b=2&a=3
http://abc.com/foo.html?a=3&a=1&b=2
false


http://abc.com/foo.html?a=3&b=2&a=1
http://abc.com/foo.html?a=3&a=1&b=2
true


https://abc.com/foo.html?a=3&b=2&a=1
http://abc.com/foo.html?a=3&a=1&b=2
false

There are also some unit tests commented out for the helper methods in the file.
