Description: An Expression Tree is a data structure that represents mathematical or logical expressions in a hierarchical form. Each node of the tree corresponds to an operator or an operand, where the child nodes represent the operands of that operator. This representation allows for the decomposition of complex expressions into simpler parts, facilitating their evaluation and manipulation. In programming, expression trees are fundamental for the interpretation and compilation of code, as they enable compilers and interpreters to analyze and optimize expressions efficiently. Expression trees are particularly useful in implementing expression evaluation algorithms, where techniques such as pre-order, in-order, or post-order traversal can be applied to compute the result of the expression. Furthermore, their hierarchical structure allows for the representation of not only arithmetic operations but also logical operations and more complex functions, making them a versatile tool in the field of programming and software development.
