Task-Scheduler-Application

This is a task scheduling application using DSA principles such as AVL tree, priority queue (heap), Json files.
The Task Scheduler Application is a Tkinter-based desktop tool designed to help users manage tasks efficiently.
It allows users to add, update, delete, and search for tasks while providing an intuitive interface to visualize tasks in a tabular format.
Each task includes attributes like name, deadline, and priority, with automatic calculation of days remaining until the deadline.
This application is suitable for personal task tracking and offers a reliable, user-friendly way to stay organized.
