Yesterday I was asked to buy some stamps.

In the land of BrainBashers, stamps are available in denominations of 3p, 9p, 11p, 17p, and 21p (just the five different values).

For three denominations of stamp I was asked to buy eight of each, and for the other two denominations I was asked to buy nine of each.

Unfortunately, I forgot which I was supposed to buy eight of, and which to buy nine of!!

Luckily I had been given the exact money required to buy the stamps, £5.00, so the shopkeeper was able to work out the stamps I needed.

Which stamps did I have to buy?

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?

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

Note: this puzzle is not interactive, and the safe buttons cannot be clicked.
