Program to convert Infix notation to Expression Tree

WebAn expression tree is a special type of binary tree that is used to store algebraic expressions. In an expression tree, each internal node corresponds to the operator and each leaf node corresponds to the operand. Consider the algebraic expression given as: X = (a + b) - (c * d) . This can be represented using a binary tree as follows: WebAlgorithm:parse (e) Input:expression string e Output:root of expression subtree for e node = make new tree node. // Bottom-out: it's a number2. 3. node.value = number extracted from string 4. returnnode endif// Recurse6. 7. node.left = parse (substring of e to the left of op) 8. node.right = parse (substring of e to the right of op)
