Jumping Coins (Posted on 2004-10-18) Difficulty: 2 of 5
There are 10 coins laid out on a table in a straight line
* * * * * * * * * *
1 2 3 4 5 6 7 8 9 10
The goal is to get 5 stacks of 2 coins each in only 5 jumps.
A coin must jump over exactly 2 other coins and land on a third.
Coins may jump in either direction.

Example:
Jump 1: Jump coin 10 on top of coin 7.
Jump 2: Jump coin 8 on top of coin 6. This is possible since coin 7 and 10 now form a stack of two coins.
