Web1 Let's say I have the following postfix expression : 5372-*- I want to create a binary tree from this expression. My algoritm is : If my char is number put it into a stack if it is an operator pop two elements from the stack and make them the childs of the operator. Then push the operator into the stack. WebAug 12, 2024 · An expression tree is a graphical representation of an expression where: leaf nodes denote constant values or variables. internal nodes contain operators. For example, here’s the above expression’s tree: Since the order of computation is clear in postfix notation, it doesn’t need parentheses. That makes postfix expressions easier to write.

WebJul 30, 2024 · An expression tree is basically a binary tree which is used to represent expressions.
