Question 2 - MCQ Questions - Chapter 3 - Stacks

Last updated at March 16, 2022 by

Which of the following is not an inherent application of stack?

A. Reversing a string

B. Evaluation of postfix expression

C. Implementation of recursion

D. Job scheduling

 

Answer:

Applications of Stack are:

  1. To reverse a string
  2. To handle matching of parentheses.
  3. Memory Management.
  4. Evaluation of postfix/prefix expressions.
  5. Implementation of recursion.

Checking the options

  • (A) Reversing a string - We can reverse a string using a stack. So, this is an application of stack.
  • (B) Evaluation of postfix expression   - We can evaluate postfix expressions using a stack. So, this is an application of stack.
  • (C) Implementation of recursion - Recursion can be implemented using a stack. So, this is an application of stack.
  • (D) Job scheduling - So, this not a application of stack

So, the correct answer is (D)
