Across a stream runs a row of eight stepping stones. On one side of the stream, on the first five stones, sit five girl lizards-Liza, Lizzie, Lottie, Lola, and Liz-and they want to get across to the other side. There's one empty stone in the middle. On the other side are three boy lizards, waiting to come across the other way-Lonnie, Leo, and Len. Only one lizard moves at a time. Any lizard may hop to the next stone if it is empty, or may hop over one lizard of the opposite sex onto an empty stone.
Can you get all the lizards across the river, and what's the smallest number of leaps?

Use these rules as a guide, 1. Do not move a boy next to another boy--or a girl next to another girl--until you reach the other side, 2. Step if you can, hop if you can not step, 3. Once you have moved a girl, keep moving girls till you have to stop, then move boys till you have to stop. The quickest has 23 leaps.

There are four people in an adventure race that need to get across a lake. They have a small canoe. The rules say that only the slowest person in the canoe can paddle, only one or two can be in the canoe at a time, and they must all cross in the canoe. From practice, they know that: Arnav can paddle across in 1 minute. Bilal can paddle across in 2 minutes. Suresh can paddle across in 5 minutes. Mohan can paddle across in 10 minutes.
How do they get everyone across the river in the fastest time without breaking the rules?
