What term describes the addition of an element to a data structure?

The term that describes the addition of an element to a data structure, specifically in the context of stack data structures, is "Push." When you perform a push operation, you are placing a new element on top of the existing elements in the stack, effectively increasing the stack's size and modifying its state.

In stack terminology, the operations involved include pushing (adding an element) and popping (removing the top element). This helps manage data in a Last-In-First-Out (LIFO) manner, where the most recently added element is the first one to be removed.

While "Enqueue" is also a term used in data structures, it specifically refers to adding an element to the end of a queue, which operates under a First-In-First-Out (FIFO) principle. Understanding these definitions is crucial for effectively using and implementing different data structures in programming.
