Explanation
Solution
In Computer Science, a specific type of binary tree is used to represent mathematical expressions.
-
Definition: An Expression Tree is a binary tree in which the internal nodes correspond to operators (like +, −, ∗, /) and the leaf nodes correspond to operands (like constants or variables).
-
Properties: * The structure of the tree naturally reflects the order of operations (precedence).
-
An In-order traversal of this tree produces the Infix expression.
-
A Post-order traversal produces the Postfix (Reverse Polish Notation) expression.
-
A Pre-order traversal produces the Prefix (Polish Notation) expression.
Conclusion
The correct term for a tree representing an arithmetic expression is an expression tree.
The correct option is (d).
