What is the primary disadvantage of storing data in a singly linked list compared to an array?
Understand the Problem
The question is asking about the primary disadvantage of storing data in a singly linked list in comparison to an array, focusing on aspects like access methods, data size, retrieval times, and memory usage.
Answer
Singly linked lists lack random access, requiring O(n) time to access elements.
The primary disadvantage of storing data in a singly linked list compared to an array is the lack of random access, which means that accessing an element requires O(n) time because the list must be traversed from the beginning, unlike arrays that allow O(1) random access.

The primary disadvantage of storing data in a singly linked list compared to an array is the lack of random access, which means that accessing an element requires O(n) time because the list must be traversed from the beginning, unlike arrays that allow O(1) random access.
More Information
Singly linked lists are dynamic and flexible in terms of memory, offering better performance for insertions and deletions compared to arrays. However, their lack of direct element access makes them slower for operations requiring element retrieval.
Tips
A common mistake is assuming linked lists allow fast element access like arrays. Remember that arrays support constant-time access, while linked lists require traversal.
