Solution

To determine which option is not an application of a stack, let's analyze the given options:

  1. Evaluation of Postfix Expression: Stacks are commonly used in evaluating postfix expressions because they can hold intermediate results. When processing a postfix expression, operands are pushed onto the stack, and when an operator is encountered, the required number of operands can be popped for computation.

  2. Balancing Symbols: Stacks are perfect for this application as well. They can be used to keep track of opening and closing symbols (like parentheses or brackets) in expressions to ensure they are properly balanced.

  3. Conversion of Infix to Postfix: This operation also relies on stacks. The Shunting Yard algorithm, developed by Edsger Dijkstra, uses a stack to help reorder the operators and operands from infix notation into postfix notation.

  4. None: This option would imply that all the previous applications are valid uses of stacks, which needs to be assessed.

Final Answer

Considering the analysis above, none of the provided options is an application that does not utilize a stack. Hence, the correct answer is none. All listed options are valid applications of a stack.
