Create a simple text editor that allows users to input, edit, and display text. This mini

project involves handling strings, user input, and dynamic memory management.

Features:

Allow the user to input multiple lines of text.

Provide basic editing commands like insert, delete, and display.

Implement a dynamic buffer to store the text, simulating heap memory management.

Implementation Details

$1.$ Mini Project Setup

Create a new MIPS assembly file in MARS.

Define data structures and initial settings for the text buffer.

$2.$ User Interface

Display a menu with options: Insert text, Delete text, Display text, and Exit.

Use syscalls for user input and output.

$3.$ Text Buffer Management

Implement functions to handle dynamic allocation for the text buffer.

Ensure that the buffer can grow as more text is added.

$4.$ Text Editing Operations

Insert: Add text at a specified position.

Delete: Remove text from a specified position.

Display: Show the current content of the text buffer.

Undo Operation: Implement an undo feature to revert the last text modification.

Find and Replace: Allow the user to search for a substring and replace it with another

string.

Cursor Navigation: Implement cursor$-$based text navigation and editing $($insert$/$delete at

cursor position$)$
