/*

In the C# file, write a program to perform a GET request on the route https://coderbyte.com/api/challenges/logs/web-logs-raw which contains a portion of web server logs. Each line begins with a date, e.g. Apr 10 11:17:35. Your program should do the following:

​

Some of the log entries have a string that contains ?shareLinkId=[ID]. You should collect all of the unique ID's from that string and return all of them in string format with each ID on its own line. If an ID appears more than once, append :N to the end of the ID where N is the number of times it appears. 

​

For example, your output could look like the following:

​

 69dff0hb32a0nv

​

 tosrvsdse4v8q8q:3

​

 4esiramcsayu0:2
