Question

Which is the application of stack ?

• A. Function call
• B. Large number Arithmetic
• C. Evaluation of Arithmetic expressions
• D. All of these

Hint:

Anytime you have a process that involves "going back" in the reverse order of how you came, like backtracking in a maze or hitting the "undo" button, a stack is likely the right data structure for the job.

Answer 1

The Correct Option is D

Step 1: Analyze the applications of a stack. A stack's LIFO (Last-In, First-Out) property makes it suitable for many computational tasks.

(A) Function call: Compilers use a "call stack" to keep track of function calls. When a function is called, its information is pushed onto the stack; when it returns, it's popped off.
(B) Large number Arithmetic: Stacks can be used to perform arithmetic on numbers that are too large to fit into standard data types by processing them digit by digit.
(C) Evaluation of Arithmetic expressions: Stacks are essential for parsing and evaluating expressions, particularly for converting expressions from infix to postfix notation and then evaluating the postfix expression.

Step 2: Conclude based on the analysis. Since all the listed options are valid and common applications of the stack data structure, the correct answer is "All of these".
