Mavzu : Binar daraxtlar bilan ishlash.

1. 
   Daraxtning balandligini aniqlashni o’rganganimizdan keyin uning muvoza-natlanganligini tekshirish mumkin. Binar daraxtning muvozanatlanganligini tekshirish uchun uning har bir tugunini har ikkala qismdaraxti balandliklarini hisoblab, farqlarini tekshirib ko’rish kerak. Agar farq 0 yoki 1 ga teng bo’lsa, bu muvozanatlangan daraxt hisoblanadi. Quyida binar daraxtni muvozanatlanganlikka tekshirishning rekursiv funksiyasini qo’llovchi dastur keltirilgan.

Yuqorida keltirilgan bir nechta algoritmlarni qo’llab bitta misol ko’rib chiqamiz.
berilgan binar daraxtning balandligini aniqlang va muvozanatlang.
