Program Server
เมื่อกดปุ่ม "Generate number & Send data" โปรแกรม Server จะ Random เลขมา 10 ตัว (ไม่เกิน 4 หลัก) หลักจากนั้นนำมาเรียงจาก น้อยไปมาก ให้เห็นบนโปรแกรม
สามารถกดปุ่ม "Generate number & Send data" ได้ไม่จำกัดจำนวนครั้ง
Program Client
เมื่อได้ข้อมูลจาก Socket ให้นำตัวเลขทั้ง 10 ตัวที่เรียงจากน้อยไปมาก มาแบ่งครึ่งเพื่อแสดงผล ตามรูปภาพ
