+| Nile  |  6650  |  Africa  |
+| Amazon  |  6400  |  South America  |
+| Yangtze  |  6300  |  Asia  |
+| Mississippi  |  6275  |  North America  |

+| Yellow River  |  5464  |  Asia  |
+| Ob  |  5410  |  Asia  |
+| Paraná  |  4880  |  South America  |
+**Objective:** Arrange the rivers in alphabetical order
+**Transformation parameters:**
