Answer 2

Prefix and Postfix :

Explanation:

• Prefix: An expression is said to be the prefix expression if the operator appears in the expression before the operands.
• Postfix: An expression is termed the postfix expression if the operator appears in the expression after the operands.

Steps for infix to prefix conversion:

• Step 1: Reverse the infix expression i.e A+B*C can become C*B+A. Note while reversing every '(' will become ')' and every ')' becomes '('.

• Step 2: Obtain the “nearly” postfix expression of the changed expression i.e CB*A+.

• Step 3: Reverse the postfix expression.

Steps for infix to postfix conversion:

• Step 1: Scan the given Infix expression from the left to right direction.

• Step 2: Initialize an empty stack.

• Step 3: If the incoming character is an operand, add it to the postfix string.

• Step 4: If the incoming character is an operator and push the character to stack if the stack is empty.

∴ According to above rule,

Infix Expression: 11 + 20/5* ( 20 - 15 )^6^5

Postfix  Expression: 11 20 5 / 20 15 - 6 5 ^ ^ * +

Prefix Expression: +11 / 20*5^ - 20 15 ^65
