  Post-fix  + Prefix + Evaluation of Post-fix Post-fix  Algorithm Infix to Postfix Conversion (Algorithm): (Pseudocode) 1)  Examine the next element in the input. 2)  If it is operand, output it. 3)  If it is opening parenthesis, push it on stack. 4)  If it is an operator, then 4.1) If stack is empty, push operator on stack. 4.2) If the top of stack is opening parenthesis, push operator on stack 4.3) If it has higher priority than the top of stack, push operator on stack. 4.4) Else pop the operator from the stack and output it, repeat step 4 5)  If it is a closing parenthesis, pop operators from stack and output them until an opening  parenthesis is encountered. pop and discard the opening parenthesis. 6)  If there is more input go to step 1 7)  If there is no more input, pop the remaining operators to output.   For example, Suppose we want to convert 2*3/(2-1)+5*3 into Postfix ...
