Slice a list to get first and last three items

Summary

Return the first three and last three items of a list as a pair of lists; if the list has three or fewer items, return the list for both positions.

Problem statement

Implement slice_first_last_three(lst) that returns a tuple (first_three, last_three) where first_three is the first three items of lst and last_three is the last three items. If lst has length 3 or less, return (lst, lst). This exercises slicing and edge-case handling.

Task

Practice list slicing to extract fixed-size segments and handle short lists gracefully.

Examples

Input format

A single list lst passed to slice_first_last_three(lst).

Output format

A tuple of two lists: (first_three, last_three).

Constraints

Do not modify the original list. If len(lst) <= 3, return (lst, lst).
