$1.$ Imagine you are designing a text editor application. The application should support the functionality of undo and redo operations using a stack data structure. Discuss and design the data structures and algorithms necessary to implement these features efficiently. Consider scenarios such as inserting, deleting, and modifying text, and how these operations should interact with the undo and redo functionalities. Additionally, propose strategies for optimizing memory usage and improving the overall performance of undo and redo operations in your design. I want pseudocode and c program
