StackStrukturen

StackStrukturen is a fundamental data structure in computer science that follows the Last-In, First-Out (LIFO) principle. Imagine a stack of plates; you can only add a new plate to the top and can only remove the topmost plate. This analogy perfectly illustrates how a stack operates. The primary operations associated with a stack are push, which adds an element to the top of the stack, and pop, which removes and returns the top element. Another common operation is peek, which allows you to view the top element without removing it.

Stacks are implemented using various underlying data structures, most commonly arrays or linked lists. The choice of implementation can affect performance characteristics, such as the speed of push and pop operations. Stacks have numerous applications in computing. They are crucial for managing function call execution through the call stack, where function calls are pushed and returned values are popped. They are also used in parsing expressions, undo/redo functionalities in software, and in algorithms like depth-first search. Understanding StackStrukturen is essential for comprehending how many computer programs manage data and control flow.
