Answer:
C) 1 4 2 / + 1 + 2 + 3 * 2 /
Explanation:
Infix, Postfix and Prefix are 3 different ways of writing expressions which differ in relative placement of operator and operands.
In Infix , operator lies between the operands whereas in postfix operator is written after its operands.
For example: 1 + 2 is infix while 1 2 + is the corresponding postfix expression.
Converting the given infix expression (1 + 4 / 2 + 1 + 2) * 3 / 2 to postfix:
Let (1 + 4 / 2 + 1 + 2) be represented by x.
Converting x to postfix:
(1 + 4 / 2 + 1 + 2) => 1 4 2 / + 1 + 2 + ------------------------- (1)
So the overall infix expression becomes:
x * 3 / 2
Converting it to postfix:
x 3 * 2 /
Replacing the value of x from (1)
1 4 2 / + 1 + 2 + 3 * 2 /
