There are 3 coins on the table: 2 quarters and 1 nickel. The nickel is between the quarters. The problem is to place one of the quarters in the middle instead of the nickel. When moving the coins you need to follow the rules: 1. The left quarter can be moved but not touched.
2. The middle nickel can not be moved, but can be touched.
3. The right quarter can be both moved and touched.
To make it easy, the resulting coins may not be touched as tightly as shown in the figure.
