You're working on a memory-constrained system where memory allocation and deallocation need to be optimized. How would you implement a memory-efficient linked list?
- Implement a singly linked list with node reuse by maintaining a free list of deleted nodes.
- Implement a doubly linked list with a circular structure to reduce memory overhead.
- Implement a hybrid linked list structure where the first few nodes are stored in an array for quick access and the rest are in a traditional linked list.
- Implement a memory pool-based linked list where nodes are pre-allocated from a fixed-size pool and reused for subsequent operations.
Option 4 suggests using a memory pool-based linked list, which optimizes memory usage by pre-allocating nodes from a fixed-size pool. This approach reduces the overhead of frequent memory allocations and deallocations, improving efficiency in a memory-constrained environment.
