Dastur natijasi:

a=-20	a=-700	a=3
a=1	a=-6	a=7
a=40	a=2	a=10

Izoh: 1.Saralash ustun bo’yicha o’sish tartibida amalga oshirildi. Agar kamayish tartibi kerak bo’lsa if ichida > belgisi bo’ladi. 2. Agar saralash qator bo’yicha kerak bo’lsa, j indeks o’zgartiriladi.

2. “Puffakchalar” usuli, ya’ni masssiv elementlaridan eng engili oldinga o’tib, og’irlari keyinga o’tadi. Bu usulda ham saralash ustun yoki qator bo’yicha olib borilishi mumkin. Bizga bitta bo’sh joy kerak bo’ladi (o’rin almashtirish uchun). Masalan: 2ta qator va 4ta ustunga ega massiv berilgan. Uning elementlarini ustun bo’yicha kamayish tartibida saralash dasturini tuzing.
