15-Laboratoriya mashg’uloti Bog'langan ro'yxat. Ikkala bog'langan ro'yxat bilan ishlash

#Misol. 5
2 ta alohida bog'langan ro'yxat berilgan. Berilgan ikkita bog'langan ro'yxatni birlashtirish uchun funktsiyani hosil qilamiz ketma-ket o’sish tartibda

List1: 10->15->17->20

List2: 5->9->13->19
Natija: 5->9->10->13->15->17->19->20

Yuqoridagi dasturni kompilyatsiya qilganingizda va bajarganingizda. U quyidagi natijani hosil qiladi

Birinchi tartiblangan ro'yxat:
10 15 17 20
Ikkinchi tartiblangan ro'yxat:
5 9 13 19
Yakuniy tartiblangan ro'yxat:
5 9 10 13 15 17 19 20
