Explain what are Infix, Prefix and Postfix Expressions?
Infix, prefix, and postfix expressions are different ways of representing mathematical or logical expressions. Here's an explanation of each:
In an infix expression, the operator is written between the two operands. This is the most common and intuitive way for humans to write expressions. For example, the infix expression for addition would be "A + B"[1][4].
In a prefix expression, the operator is written before the two operands. It is also known as a "Polish notation". For example, the prefix expression for addition would be "+ A B"[1][2][5].
In a postfix expression, the operator is written after the two operands. It is also known as a "Reverse Polish notation". For example, the postfix expression for addition would be "A B +"[1][4][5].
The main differences between these notations are:
