Concept of flowchart

A flow chart diagram is a collection of symbols that represents the steps involved in a process. It is a generic tool that can be adapted for various purposes. It is one of the most common process analysis tools. It is used for the graphical analysis of an algorithm. It helps to represent the flow of the process from the input to output. A flowchart that represents the workflow of activities is known as an activity diagram.There are so many ways that can help people to understand computer technologies and their applications. One of them is a flowchart diagram.

Question

### Evaluating a Postfix Expression

**Problem Statement:**

Evaluate the following postfix expression:

```
3 5 5 * + 5 7 + 6 / -
```

**Choices:**

The value of the above postfix expression is:
- a. 26
- b. 22

**Instructions:**

1. **Use the Stack**:
- Use the stack provided to fill (push) in numbers.
- Type "pop" beside the number when you need to pop it out.
2. **Find the Value**:
- Finally, find the postfix expression value.

**Steps to Solve:**

- Write a step-by-step procedure to solve the problem in the provided space:

```
Your Answer is ______ (a or b)
```

**Diagram Explanation:**

- **Stack Representation**:
- A visual stack diagram with empty slots, intended for sequential operations to evaluate the expression.

- **Functionality**:
- Follow the order of operations typical for postfix expressions, pushing numbers to the stack and applying operations where needed, popping after each operation.

This educational problem helps understand postfix expressions and their evaluation.
