Each line of instructions corresponds to one button press. Always start at the number 5. Each button to be pressed can be found by starting on the last button pressed and moving to the adjacent buttons on the keypad: U moves up; D moves down; L moves left; and, R moves right. For example, if your instructions are: UUUUULLLLL DRRRRDDDD LDDDDDDDD UURRRRRRR you start at 5 and move up to 2. Since you can't go up any further on the keypad you stop at 2. Now, move teft to 1. Again, since you can't go left any further on the keypad, you stop at 1. So, your first button is 1. Starting at the last button pressed, you now move down one button to 4 then right two times to 6 and down once to 9. So, you now end up at 9, your second number. Continuing on from 9, you move left one and down one to e. Your third number is e. . Finally, from you move up two to 5 and right one to 6. Your last number is 6, So, given the above instructions, the code for the bathroom key-lock is 1986
