Convert the infix expression A * (B + C) / D to a postfix expression

To convert the infix expression A * (B + C) / D into postfix notation, we use the following rules:

Operator Precedence: Parentheses have the highest precedence, followed by multiplication (*) and division (/), and then addition (+).
Associativity: Operators like * and / are left-associative, meaning operations are performed left to right if they have the same precedence.
Conversion Rules:
- Operands (like A, B, C, D) are output immediately.
- Operators are pushed onto a stack.
- Parentheses dictate the priority: Solve what's inside the parentheses first.

Start with the subexpression inside the parentheses (B + C):
- Convert B + C to postfix: BC+.
Substitute the postfix for (B + C) back into the original expression:
- The expression becomes A * BC+ / D.
Process the multiplication (*) and division (/):
- A * BC+ becomes ABC+*.
- ABC+* / D becomes ABC+*D/.
