Hacker Rank 3: Oh surprise, more regex. (I'm just joking, I can't remember the title but let's called file processing). Given a text file containing network connections information (space separated) like this: something - - "GET something something" [another thing with spaces in the middle] 4500 where: something = first column - = second column - = third column "Get something...." = forth column and so on. The last column, 4500 represents the number of bytes transmitted. You need to filter the records where a number of bytes are bigger than 5000 and the sum of bytes of those records.
