### Evaluation of Postfix Expressions Using a Stack
#### Problem Statement
Evaluate the following postfix expression using a stack (show detailed steps):
\[ 5\ y\ 1\ +\ \log\ \times\ a\ 5\ \div\ - \]
#### Note:
- The characters **'y'** and **'a'** are considered as variables.
- The symbols **'log', '+', '-', '×', '÷'** are considered as operators.
---
### Detailed Steps
1. **Initial Stack State:**
- **Empty Stack**
2. **Reading from Left to Right:**
\[
\begin{array}{|l|c|}
\hline
\text{Expression Element} & \text{Stack State} \\ \hline
\ 5 \ & [5] \\ \hline
\ y \ & [5, y] \\ \hline
\ 1 \ & [5, y, 1] \\ \hline
\ + \ & [5, y + 1] \\ \hline
\ \log \ & [5, \log(y + 1)] \\ \hline
\ \times \ & [5 \times \log(y + 1)] \\ \hline
\ a \ & [5 \times \log(y + 1), a] \\ \hline
\ 5 \ & [5 \times \log(y + 1), a, 5] \\ \hline
\ \div \ & [5 \times \log(y + 1), a \div 5] \\ \hline
\ - \ & [5 \times \log(y + 1) - (a \div 5)] \\ \hline
\end{array}
\]
3. **Final Stack State:**
- **[5 × log(y + 1) - (a ÷ 5)]**
The final result of the evaluation process is **\[5 \times \log(y + 1) - (a \div 5)\]**.
