ลอง code บ้านๆ ซักตัวเผื่อดูว่าใครจะอยู่หรือไป

25Jun10

มันเกิดปัญหาเมื่อผมอยากรู้ผลว่า สเปนจะเข้ารอบได้อย่างไร นั่งเขียนกระดาษ พิมพ์ notepad ก็ดูไม่เห็นภาพ เลยนึกจะเขียน code ครับ ก็เลยลองดู basic พื้นฐาน + พื้นมั่วครับ (-/\-)

จากสถานการณ์จริงของกลุ่มนี้ คะแนน ลูกได้เสียจริง
และผมคิดว่าถ้าจบลงด้วย

Spain 2 – 0 Chile
Switzerland 2 – 0 Honduras
