Get started now by creating a new collection.
What if you array.Length is greater than 4?
HAHAHAHAHA that was hilarious!! You completely screwed the system!! Way to think outside the box!
really smart!
this looks very much like C code.
amazing solution!!!!!
*board checks rows.
*board.transpose checks columns
then you have a little loop to check 3x3 squares
unpack all of those and pass them to #all? and make sure they are all equaled to 1..9 sorted.
flawless...
Thanks!
unbelievably amazing solution.
damn! I was certain there were no easy way to solve this one! I ended up with bloated code! (I didn't know about the #each_cons method)
this is definitely the way to go.
rubocop would issue a
perceived cyclomatic complexity is too highwarningAlmost the same as my solution! You would get the same results if you included only 1 hash per opposite directions rather than both. ie) [{k, v}] rather than [{k,v}, {v, k}]
