An infix expression is a single letter, or an operator, proceeded by one infix string and followed by another
infix string.
e.g. <b>A,A + B,(A + B) + (C – D)</b>.So,in which we have operators between operands.And postfix expression
(also called Reverse Polish Notation)
is a single letter or an operator, preceded by two postfix strings. Every postfix string longer than a single
variable contains first and
second operands followed by an operator.e.g. <b>A,A B +,A B + C D –</b></p>

<p class="text-light text-monospace my-4 mx-2">To convert infix expression to postfix expression, computers
usually use the stack data structure.
By scanning the infix expression from left to right, when we will get any operand,
simply add them to the postfix form, and for the operator and parenthesis, add them in the stack maintaining
the precedence of them.So,
here you can convert infix expression to postfix by just entering infix expression.Checkout examples that are
