FCFS Scheduling Algorithm in Python

This project implements the First Come First Serve (FCFS) CPU scheduling algorithm using Python.
It simulates how processes are executed based on their arrival time and calculates:

• Completion Time
• Turnaround Time
• Waiting Time

---

📌 What is FCFS?

FCFS (First Come First Serve) is a non-preemptive scheduling algorithm where the process that arrives first gets executed first — just like a queue.

---

🧠 Input Format

Each process is written as:

[arrival_time, burst_time, process_id]

---

Example:

process_list = [ [2, 6, "p1"], [5, 2, "p2"], [1, 8, "p3"], [0, 3, "p4"], [4, 4, "p5"] ]

---

📊 Output Example

['p4', 'p3', 'p1', 'p5', 'p2'] {'p4': [3, 3, 0], 'p3': [11, 10, 2], 'p1': [17, 15, 9], 'p5': [21, 17, 13], 'p2': [23, 18, 16]}
