Sliding pennies #1 (Posted on 2005-05-31) Difficulty: 3 of 5
Six pennies are arranged in the pattern of O's below.

    O O O
   O O O

Nearby pennies are touching. By the fewest number of legal moves, transform the pattern into the pattern

O O O O O O

consecutive pennies touching. A legal move consists of sliding a penny, not picking up a penny, without disturbing the other pennies, to a new position touching at least two pennies. (You might want to look up Moving Quarters for a similar problem with the same rules.)
