Puzzle 179
This BrainBashers safe has a rather unusual control panel.
In order to open the safe, you have to press every single square once only, in the correct sequence, ending on the square marked E.
Each square indicates which square to press next, for example, 2U means move up 2 squares and 3R means move right 3 squares.
Can you determine which square you must start with?
| 6R | 4R | 3D | 2D | 2L | 2L | 2D |
| 2D | 1U | 4R | 4D | 3L | 2L | 2L |
| 1U | 1R | 3R | 3L | 2U | E | 2D |
| 1R | 1U | 3R | 1D | 2D | 1L | 3L |
| 4U | 1L | 3U | 2D | 2U | 3U | 2D |
| 1D | 1U | 1D | 3L | 2R | 3L | 2U |
| 1R | 1U | 2U | 2R | 2U | 1U | 2L |
Note: this puzzle is not interactive, and the safe buttons cannot be clicked.

I am compiling the BrainBashers world almanac and it now contains quite a few pages. But just how many?
I know that it takes 121 digits to print all of the page numbers in sequence.
So, how many numbered pages does the book have, and how many times does the number 9 appear?
