Difference Between Pointer and Reference | Dataford Interview Questions

What is the difference between a pointer and a reference?

Asked in the Round 1 stage. Demonstrate the distinction by simulating one pointer and one reference that initially refer to the same integer object.

Implement simulate_pointer_reference(initial_value, operations). Each operation is a dictionary with kind equal to pointer_rebind, pointer_write, or reference_write, and write operations include an integer value. A pointer rebind makes the pointer refer to a new object, while a reference write always modifies the original object. Return a dictionary containing original_value, pointer_target, pointer_value, and reference_value.

Constraints

0 <= len(operations) <= 10^4
Values are integers
Operations contain valid kinds and required values

Function Signature

def simulate_pointer_reference(initial_value, operations):
