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?

1D	6D	2R	3R	3L	5D	1L
1R	E	1U	3R	1R	3L	2D
2U	1D	2L	2U	1L	2D	1L
2D	2R	1D	3L	2U	3L	1D
1R	1D	2R	2D	1L	2D	1D
3R	1R	3U	4U	2U	1L	1D
2U	1R	2L	1R	4U	3U	4U

Painter Pete, our local DIY expert, is renovating the local hospital.

He has to number each of the rooms in the hospital with plastic numbers.

However, he has run out of the number 9.

Unfortunately, he has no spare 6's available, which certainly would have been useful.

How many 9's must Pete buy in order to number all 1,000 rooms?
