What all is true about Stack data structure? (More than one option is ...
Introduction:
The stack data structure is a fundamental concept in computer science that follows the Last In First Out (LIFO) principle. It allows for efficient insertion and deletion of elements at one end, known as the top of the stack. Let's discuss the true characteristics of a stack.
Last In First Out:
One of the key properties of a stack is that it follows the Last In First Out (LIFO) principle. This means that the last element inserted into the stack will be the first one to be removed. When a new element is added to the stack, it becomes the new top, and any subsequent elements are placed on top of it. Similarly, when an element is removed, the top element is removed first.
Minimum 2 Queues not required:
The statement that a minimum of 2 queues is required to implement a stack is incorrect. While it is possible to implement a stack using two queues, it is not a necessary requirement. In fact, there are multiple ways to implement a stack, including using arrays, linked lists, or a combination of both.
Does not have a fixed size:
Unlike some other data structures, such as arrays, a stack does not have a fixed size. It can dynamically grow and shrink as elements are added or removed. This allows for flexibility in handling varying amounts of data without the need for preallocating a specific amount of memory.
Summary:
In summary, the true characteristics of a stack data structure are that it follows the Last In First Out (LIFO) principle, does not require a minimum of 2 queues for implementation, and does not have a fixed size.
