What is an array?
What is an array?
A data structure where elements are arranged sequentially, each accessed by its index (position).
What is a linked list?
What is a linked list?
A data structure where elements are connected in a linear sequence, but stored at different memory locations. Each element points to the next.
What is a stack?
What is a stack?
A data structure that follows the Last-In-First-Out (LIFO) principle. The last element added is the first one removed.
What is a queue?
What is a queue?
A data structure that follows the First-In-First-Out (FIFO) principle. The first element added is the first one removed.
