How to Use

1. Select a scheduling algorithm (FCFS, SJF, SRTF, Priority, RR)
2. Enter process details:
   • Arrival Time
   • Burst Time
   • Priority (if required)
3. Enter Time Quantum (only for Round Robin)
4. Click Solve
5. View results:
   • Gantt Chart
   • Completion Time
   • Turnaround Time
   • Waiting Time
   • Average metrics

Project Overview

This project simulates CPU scheduling algorithms used in Operating Systems. It dynamically takes process inputs, executes the selected scheduling algorithm on the backend, and visualizes execution using a Gantt Chart along with calculated performance metrics.
