Infix to postfix using stack example
WebInfix: The expression in which the operator appears in between the operands is known as infix expression. For example, (a+b), where a and b are operands, + is an operator that appears between the operands a and b . Postfix: Similarly, the expression in which the operator appears after the operands is known as postfix expression. WebWhen the last token of infix expression has been scanned, we pop the remaining elements from stack and append them to our postfix expression.* Infix expression: K + L - M*N + (O^P) * W/U/V * T + Q Let us dry run the above infix expression and find out its corresponding postfix expression. The above string is parsed from left to right.
