WebbA postfix expression is merely the reverse of the prefix expression. Which is better, Prefix or Postfix? Postfix is better, and one of the main reasons is Memory efficiency. What is the other name for a postfix expression? A postfix notation is also known as “Reverse Polish notation”. What is the difference between infix and postfix? WebbWe simply push it into the operand or Postfix stack. Step 3: If the character encountered is : ' (' , i.e. Opening Parentheses, we push it into Operator Stack. Step 4: Now, if we encounter ')' i.e. Closing Parenthesis, we are going to pop the elements out of Operator Stack until we get the opening ' ('.

WebbGiven Infix - ( (a/b)+c)- (d+ (e*f)) Step 1: Reverse the infix string. Note that while reversing the string you must interchange left and right parentheses. Step 2: Obtain the postfix expression of the expression obtained from Step 1. Step 3: Reverse the postfix expression to get the prefix expression.
