+   |Const?|Name| Parameters| Return Type| Time Complexity| Description
+   |const|root|(size_t number)|size_t|very fast|
+   Return the *group id* of the number given
+   |const|size|()|size_t|very fast|
+   Return *N*
+   ||reset|(size_t N)|void|very fast|
+   Clean and initalize
+   ||merge|(size_t number1, +
+   size_t number2)|size_t|very fast|
+   *Union* the group contains number1 and the group contains number2.
+   Return the merged group id
+   |=======================================================================
+NOTE: *very fast* means that you can consider it as constant time.
