Access elements by positive and negative index

Summary

Retrieve an element from a list using positive or negative indexing. Return None when the index is out of range.

Problem statement

Write a function get_element(lst, idx) that returns the element at position idx in lst. Support negative indices (Python-style). If idx is out of range for lst, return None. This practices indexing and bounds checking.

Task

Implement index access that supports both positive and negative indices and safely handles out-of-range access by returning None.

Examples

Input format

Two arguments: a list lst and an integer idx passed to get_element(lst, idx).

Output format

The element at position idx, or None if idx is out of range.

Constraints

Do not raise exceptions for out-of-range indices; return None instead.
