Join Barron Stone for an in-depth discussion in this video Solution Overview, part of Code Clinic: Python.
In this video I'll give you a brief overview…of my solution to the eight queens problem…by demonstrating the user interface…and describing the approach I took.…Now the name eight queens is a bit misleading…because the program is actually able to solve…the queens problem for any number…of four or more queens.…So, I decided to call my program "N Queens" instead.…If you open up the exercise files,…and navigate to the problem three directory…you'll find a script in there called "nqueens.py".…When you run the N Queens script it'll display…a standard sized eight by eight chessboard…with one possible solution to the eight queens problem.…
The solution counter in the bottom right…tells me that this is the first of 92 possible solutions…for an eight by eight queens board.…To view other possible solutions,…just click on the "Get Next Solution" button,…and the program will cycle through…and display all possible solutions.…You can also calculate the solution to the queens problem…for a different number of queens,…and to do that just change the value…
Barron introduce challenges and provides an overview of his solutions in Python. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
Visit other courses in the series to see how to solve the exact same challenges in languages like C#, C++, Java, PHP, and Ruby.
