Button puzzle (Posted on 2006-10-13) Difficulty: 2 of 5
There are six buttons in a row. Each button shows an arrow pointing left (L) or right (R). When you press a button, all buttons in the direction of its arrow (not including itself) rotate 180 degrees.

Find the least number of button presses required to get from RRRLLL to LRLRLR.

Question Question / Clarification | Comment 1 of 6
by "all buttons in the direction of its arrow", I assume this means the buttons to the Right of the button change if you push an R button.  (and not 'all the other R buttons change to L buttons')
so if you push the 3rd button:

and not: ---> LLRLLL
