ท้าทาย

ในแต่ละ 12 วันของคริสต์มาสให้ส่งบทร้อยกรองที่เหมาะสมของ "12 วันคริสต์มาส" ตามวันที่มิฉะนั้นจะมีการร้องพร้อมกันของ "ฉันหวังว่ามันจะเป็นคริสต์มาสทุกวัน"

ขึ้นบรรทัดใหม่และ / หรือลากขึ้นบรรทัดใหม่ ( \n) และเว้นวรรคต่อท้ายได้รับอนุญาต คุณไม่สามารถอ่านจากแหล่งภายนอก

โดยทั่วไปสิ่งที่คุณต้องทำคือการอ่านวันที่ของระบบและส่งออกข้อตาม "12 วันคริสต์มาส"

ถึง
