    Cho mot mang so thuc. Viet ham su dung con tro lam tham so tra ve con tro tro toi phan tu co gia tri gan nhat voi gia tri trung binh cua mang. Test bang chuong trinh.


Code:


    Mot game doi khang cho phep tao ra cac dau thu (moi dau thu co ba chi so suc manh, nhanh nhen, va mau)
    Viet chuong trinh tao ra ba dau thu voi cac chi so ban dau tuy chon. Chuong trinh su dung ham: arena nhan tham so la cac dau si, dua ra ket qua la nguoi thang cuoc. Sau mot tran dau nguoi thang cuoc cac chi so tang 2%. Nguoi thua cuoc tang 1%. Ngoai ra mot dau si con duoc diem % thuong ngau nhien.
