When I first read through the five-house logic puzzle, I kept thinking, "I should just brute force this thing." I was so naive...

Reader Johann Preissl writes in with a pure T-SQL solution to the Five-House Logic Puzzle. No tables or VBA required!

In part 2 of my Access solution for the five-house logic problem, we test the neighborhood class module.

In part 1 of my Access solution for the five-house logic problem, I demonstrate the class module I used to model a neighborhood configuration.

In this follow-up to my post on the classic Five-House Logic Problem, I provide the solution to the riddle plus a few tips for finding it.

In part 1 of this series, I introduce a classic logic problem that took me nearly two hours to solve by hand. Later in the series, we'll use Access to program a solution.

In the second solution to my recent reader challenge, I use recursion to calculate the cumulative number of gifts given for each day of the "12 Days of Christmas."

In the first solution to my recent reader challenge, I use a loop to calculate the cumulative number of gifts given for each day of the "12 Days of Christmas."

How many total gifts does one's true love deliver by the nth day of Christmas? It's a deceptively tricky problem to solve.
