Walkthrough

Two new functions, increment and divide_by_3, were added to the module. The increment function returns its integer input plus one, while divide_by_3 returns the input divided by three as a float. The previously existing double function is unchanged.

Poem

A rabbit with numbers, quick on its feet,
Adds one, divides by three, never skips a beat.
With new mathy tricks tucked under its ear,
The code grows smarter, the logic more clear!

4-6: Add docstring to increment. Improves API clarity and documentation.

 def increment(n: int) -> int:
-    return n + 1
+    """Return the given integer incremented by one."""
+    return n + 1

Consider adding unit tests for this function to cover typical and edge cases.

7-9: Add docstring to divide_by_3. Clarify behavior and return type.

 def divide_by_3(n: int) -> float:
-    return n / 3
+    """Return the given integer divided by three as a float."""
+    return n / 3

Also add unit tests covering divisible and non-divisible inputs, negative values, and zero.
