Alphabetical logic (Posted on 2006-07-28) Difficulty: 3 of 5
What Mr. Lister lacks in memory, he makes up with logic skills. Seriously, he can't remember anything. Can you match the six first names (Dirk, Ellen, Erik, Greg, Nelson, and Tony) with the six last names (Austin, Dunn, Ives, Lister, Newton, Sumner)?

These few memories are all that remain of his enigmatic and perhaps dramatic past:

1. When listed in alphabetical order by last name,
a)Greg comes before Dirk
b)Nelson comes before Ellen
c)Tony comes before Erik

2. When listed in alphabetical order by first name,
a)Austin comes before Newton
b)Ives comes before Dunn
c)Sumner comes before Lister

That's what I did. I wrote a program. It was such a simple program that I didn't bother to save the code. It ran in zero seconds. (720 is not a large number to a software program.)
