1. Berilgan natural sonning mukammalligi, ya'ni o‘zidan boshqa musbat bo‘luvchilarining yig‘indisi shu sonning o‘ziga tengligi aniqlansin.

1.Berilgan natural sonning mukammalligi, ya'ni o‘zidan boshqa musbat bo‘luvchilarining yig‘indisi shu sonning o‘ziga tengligi aniqlansin. (misol uchun, 6- mukammal, chunki 6=1+2+3).

1. 
   4. Berilgan sonni kubini topadigan funksiya yarating. Ushbu funksiya yordanida a,b,c,d sonlarini kubini hisoblang.
   
2. 
   Berilgan ikkita sonni “do’st son” larga tekshiradigan funksiya yarating. Ushbu funksiya yordamida a va a1, b va b1, c va c1 sonlarini o’zaro do’stlikka tekshiring. Izoh: do’st sonlar deb birinchi sonning bo’luvchilari yig’indisi ikkinchi sonni, ikkinchi sonni bo’luvchilari soni birinchi sonni tashkil qilgan sonlar juftiga aytiladi.
