Convert the following infix expression to its equivalent postfix expression 

showing the stack contends for each step of conversions.

(P/(Q-R)*S+T)

Symbol	Stack	Expression
(	(	-
P	(	P
/	(/	P
(	(/(	P
Q	(/(	PQ
-	(/(-	PQ
R	(/(-	PQR
)	(/	PQR-
*	(*	PQR-/
S	(*	PQR-/S
+	(+	PQR-/S*
T	(+	PQR-/S*T
)		PQR-/S*T+

So the postfix expression is 

PQR-/S*T+
