red jujube
Find eight jujubes : (four red and four green)
I am not sure this works with other colours...try and let me know!

Draw a number line : 1 to 10
Place the jujubes in alternating colour sequence.
Leave spaces 9 and 10 open.

While moving two adjoining jujubes, without changing their sequence, rearrange them so that all the green ones will be on the left and the red ones will be on the right.
The jujubes can only occupy blank spaces.
It must be done in only four moves

Should you succeed...your reward : a jujube feast!
