Infix and postfix operation are mathematical operation if an operator is placed between two operands like x + y then this is an infix expression.
Postfix expression is an expression in which operator is written after operands like above infix can be change in postfix by this way. "x y +" and prefix is another expression in which operator is written before operands. Like "+x y"
Postfix is solved via stack.
