It looks like the easiest way to convert the expression from infix to postfix notation is to use a standard stack based algorithm (it has linear time complexity, so it is optimal) and then to build a tree (constructing a tree from postfix expression is simple because all operators are in a correct order). WebThe final result of the above expression is 7. What is Postfix expression? If we move the operators after the operands then it is known as a postfix expression. In other words, postfix expression can be defined as an expression in which all the operators are present after the operands. For example: If the infix expression is A + B * C grasslands road company
