What is the typical time complexity of accessing an element by its position in a sequence?

The time complexity of accessing an element by its position in a data sequence depends on the type of data structure:

• In Python lists (list), index access is an O(1) operation (constant time), as lists are implemented as arrays with direct access.

• In linked lists (e.g., collections.deque in Python), index access is an O(n) operation, since you need to traverse the elements sequentially.

• In tuples (tuple), index access is also O(1).

Thus, in general, for array-like sequences, access by position is a constant-time operation.
