Masala

• Masala. , , , , va elementlardan iborat bo‘lgan “Talaba” murakkab ro‘yxati tuzilsin. Hamda, ro‘yxatlar bilan ishlash metodlari va funksiyalaridan foydalanib quyidagi amallar bajarilsin:
• Qo‘shish, o‘chirish, tahrirlash va boshqa amallar bajarilsin;
• Erkaklar soni eng ko‘p bo‘lgan kurs nomeri;
• Eng ko‘p tarqalgan erkak va ayollar ismlari;
• Yoshi va ismi bir xil bo‘lgan talaba qizlar familiyalarining alfavit tartibidagi ro‘yxati;
• Ro‘yxat kurslarga ajratilsin.
