I have a list of lists derived from a log file that I want to create a
summary of, but I am not sure of an approach to do what I need.
Here's a sample of the data:
[["user1","18/Mar/2007:07:52:38 -0400"],["user1","18/Mar/2007:07:52:40 -0400"],["user2","18/Mar/2007:07:52:42 -0400"],["user3","18/Mar/2007:07:52:42 -0400"],["user2","18/Mar/2007:07:52:43 -0400"]]
What I want as output is something like this:
[["first user alphabetically","most recent timestamp for this user"],["second user alphabetically","most recent timestamp for this user"], ...]
Can anyone suggest an approach for this? Thanks.
