How do you solve this?!?

Question

7 stepping stones, 3 green frogs, 3 brown frogs.
The 3 green frogs are on the left, and can only move right. The 3 brown frogs are on the right, and can only move left. The empty stone is in the middle. Frogs can only jump over 1 other frog, onto an empty stone. How do you move the green frogs right, and the brown frogs left? This was recently on Yahoo Office Attachments.

Yes, it seems I only have an IQ of 49..........

Answer 1

Ok...

If the frogs are numbers 1 2 3 4 5 6, this is what you do. 123 on the left facing right, 456 on the right facing left.

Move each frog the way its facing in this order...

3, 4, 5, 3, 2, 1, 4, 5, 6, 3, 2, 1, 5, 6, 1

Answer 2

Move the green frog first. Then jump this with the brown frog.
Move the next brown frog to the left and leap the green frog into the gap.
Leap the green frog (second from left) over the leftmost brown frog, and then move the leftmost green frog to the right.
Leap the leftmost brown frog onto the leftmost stone and then leap the next two brown frogs into the vacated places.
The rightmost green frog can then move onto the rightmost stone.
The next two green frogs can leap onto the vacated stones.
Move the second brown frog into its final position. Leap the next one over into its position, and, finally, the last green frog can amble to its place. You're finished!
And it took me slightly more than three minutes. Doh!

Answer 3

Seems a simple question stated in a difficult way. Move all frogs of one color ONE AT A TIME to the other side. Rinse. Repeat

Answer 5

I thought it was going to be really complicated following your description, but did it in 20 seconds. Just move the first frog...what's the difficulty??

Answer 6

ok. I started off by moving the green frogs firts. If you move the brown frogs is the same just in reverse. ok.

1. hop one stone with the first green frog.
2. hop over the first green frog with your first brown frog.
3. hop one stone with your secong brown frog.
4. hop over the second brown frog with your first green frog.
5. hop over the first brown frog with your second green frog.
6. hop one stone with your third green frog.
7. hop over the third green frog with you first brown frog.
8. hop over the second green frog with your second brown frog.
9. hop over the first green frog with your third brown frog.
10. hop one stone with your first green frog.
11. hop over the third brown frog with your second green frog.
12. hop over the second brown frog with your third green frog.
13. hop one stone with your second brown frog.
14. hop over the third green frog with your third brown frog.
15. hop one stone with your third green frog and you are done!

Answer 7

Take the stones away and let them drown

Answer 8

you have to make it jumping one stone more at the beginning! took me some time to work it out - but when you get the trick its actually easy....

Answer 9

yes i know how to solve that, but its too complicated to write down

Answer 10

I agree it is to hard to say...or maybe we just don't have the time.
