Write applications of stacks.
Answer
Stacks are vital for managing function calls, evaluating expressions, and executing backtracking algorithms.
Stacks operate strictly on a Last-In-First-Out (LIFO) architectural principle, making them indispensable for various system-level operations. Critical applications include meticulously managing nested function call memory (the Call Stack), parsing and evaluating complex mathematical expressions (infix to postfix conversion), implementing undo/redo state mechanisms in software, and executing algorithmic backtracking in graph traversals (like Depth First Search).
