Stack and Queue Applications
Queue Applications
- Printer Job Management: Jobs submitted to printer are handled in FIFO order
- Network File Servers: File access requests handled on First Come First Serve basis
- Call Centers: Calls placed in queue when all operators are busy
- Operating Systems: Process waiting queues
- Advanced Data Structures: Used to improve efficiency in various algorithms
Stack Applications
- Parenthesis Balancing: Checking if brackets are properly matched
- Expression Conversion: Converting between infix, prefix, and postfix
- Expression Evaluation: Evaluating mathematical expressions
- Function Calls: Managing function call stack
- Tree Traversal: Used in advanced data structures for traversing
Expression Evaluation
Expression Types
- Infix:
a + b (human-readable format)
- Prefix:
+ a b (operator before operands)
- Postfix:
a b + (operator after operands, computer/ALU friendly)
