Join Todd McLeod for an in-depth discussion in this video Designing our alogrithm, part of Code Clinic: Go.
- So the first step in understanding our solution…was this data structure,…and we already saw how this data structure eliminates…any conflicts between queens on horizontal…or vertical vectors.…And so a vector is just like a path way,…or an arrow pointing a certain way.…And so, on any Row or any Column,…none of the queens are going to conflict.…And so we have that data structure where none of the queens…are going to conflict,…could we somehow find all of the different…permutations of this data structure?…What do I mean by permutations?…So let's say the data structure only had A and B.…
What are the permutations of A and B?…So maybe pause this video…if you need to reflect on that question…because I know I'm a fast talker,…and you need to take this point away.…Step one, we got this data structure…that eliminates Row and Column conflicts.…Now, can we find all the different permutations?…All the different arrangements of these eight digits…in this data structure,…can we find all of the different arrangements…and combinations of that?…
Todd introduces challenges and then provides overviews of his solutions in Go. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
