Question 1 of 40Assessment

What is the primary operational advantage of an XOR linked list over a traditional doubly linked list in embedded systems programming?

A. It allows for bidirectional traversal while only requiring one bit of storage for the direction flag per node.

B. It enables constant-time concatenation of two lists without needing to update the internal pointer addresses.

C. It prevents the need for sentinel nodes, thereby reducing the total memory footprint of the data structure.

D. It reduces memory usage by storing the bitwise XOR of the previous and next pointers in a single field.
