Computer Science
Which of the following applications may use a Stack?
- A parentheses balancing program
- Tracking of local variables at run time
- Compiler Syntax Analyzer
- All of these
Answer
All of these
Reason — Stacks, with their last-in-first-out (LIFO) functionality, are important in parentheses balancing programs, tracking local variables at runtime for efficient memory management, and compiler syntax analyzers for parsing expressions and managing program flow.
