so what was the solution? i am also using pythong and getting True for False in performance testing

I am still getting same error in version 2.7, what is solution?

Can someone explain please, why the test case is saying 'foobar001000' should equal 'foobar01000'
my code gives foobar001001 for the input foobar001000. My understanding is that you need to get the next number.

normally when you search for a key that does not exist in a list you will get an error like that

I dont understand , is this ment to be puzzle or a programming exercise. You have to explain how do you split nxm grid. There are many ways to do it.
Obvious way is do it layer by layer and then multiply the results. If you do that then a 5x5 grid would need 8 cuts for first layer and 8 for second , 8 for 3rd and 8 for 4th and 4 for last.
That means 36 cuts.

Thank you Ace, let me have a check. The code ran fine for the inputs in the problem so I assumed it was fine but I was wrong.
