here is a c code for Post-order traversal sequence and theevaluation result of the post-order stack machine.Need to implementsimilar code for Pre-order traversal sequence and the evaluationresult of the pre-order stack machine.
Example of the input binary tree from the file expression.txt: +- – 3 * – + _ _ 2 5 5 2 3 15
The output of the program of the above parsed math expressionshould be:
Pre-Order: + – 3 * 2 5 – – 5 2 + 3 15
Pre-Order Evaluation: -22
Post-Order: 3 2 5 * – 5 2 – 3 15 + – +
Post-Order Evaluation: -22
