... * (A + B)...

if i have * on the stack and '(' comes, am i supposed to pop * right away or pop it when '+' comes?

[Ghulam Rasool]

"+" sign will pop only when ")" occurs.

No, as soon as you see a (, push it on the stack.  So ( will go on top of the * operator.

it is not possible becoz operands are 2 and operators are also two. here operands should be 3. but if u want to salve it, it will be like this. AB+*
