In software development, linked lists are the next most basic data structure.
What is a Linked List?
Engineers can insert/remove elements from a linked list without re-allocating or moving the items.
Links prevent arrays from experiencing the worst-case scenario that would otherwise occur.
Another, more complex data structure commonly uses linked lists as a building block.
The operation of linked lists differs from that of arrays. A linked list stores data in nodes that are connected by pointers rather than blocks of memory.
What you need to know about linked lists for technical interviews
When inserting or deleting items from a list during technical interviews, remember to use linked lists.
When list sizes must be flexible, flexible list sizes are especially important.
The best choice for indexing is an array and the best choice for searching is a hash table.
