The numbers will criss-cross, so that digit A1 is both the first vertical number's first digit and the first horizontal number's first digit, and I9 is the same way, only replace "first" with "last." This is all the help you will get from me. Help each other, do not expect to do it by yourself. This is like Sasuke, a.k.a. Ninja Warrior; a win for one is a win for everybody. Good luck. Edit: Correction: I will help you in one scenario: If you have a question about the instructions, I will answer them. Other than that, you must rely on each other for assistance.
Livingstone Posted August 19, 2008 Posted August 19, 2008 what do you refer to as *first* , *last* *vertical* and *horizontal* numbers? in a matrix where you have not described any order and expect an order to be found! I am assuming there isnt any
dstebbins Posted August 19, 2008 Author Posted August 19, 2008 First verticle number is the number that goes vertically in the A column. Same with first horizontal, only it's row 1. Last columns and rows are I and 9, respectively. It looks like this: A1 B C D E F G H I 2- - - - - - - - - - 3- - - - - - - - - - 4- - - - - - - - - - 5- - - - - - - - - - 6- - - - - - - - - - 7- - - - - - - - - - 8- - - - - - - - - - 9- - - - - - - - - - Replace the dashes with a digit so that nine of the 18 numbers are horizontal and nine of them are vertical in a 9x9 matrix.
Kyrisch Posted August 20, 2008 Posted August 20, 2008 It's kind of like SATOR AREPO TENET OPERA ROTAS... SATOR AREPO TENET OPERA ROTAS Only with numbers...
dstebbins Posted August 20, 2008 Author Posted August 20, 2008 ^^^Exactly, for example, if I were using a 2x2 matrix, the numbers 14, 23, 12, and 43 would be arranded like this. 14 23 14 is row 1. 23 is row 2. 12 is column A, and 43 is column B. Get it?
