Ushbu blok-sxema qanday natija chiqarishini aniqlaymiz.

Boshlang‘ich qiymatlar:

S = 0
A = -6

Takrorlanuvchi jarayon:

S = A - S
A = A + 2
A > 9 shart tekshiriladi. Agar Yo‘q, jarayon yana davom etadi. Agar Ha, S chiqariladi.

Hisob-kitobni bajaramiz:

A	S = A - S	A = A + 2
-6	-6 - 0 = -6	-6 + 2 = -4
-4	-4 - (-6) = 2	-4 + 2 = -2
-2	-2 - 2 = -4	-2 + 2 = 0
0	0 - (-4) = 4	0 + 2 = 2
2	2 - 4 = -2	2 + 2 = 4
4	4 - (-2) = 6	4 + 2 = 6
6	6 - 6 = 0	6 + 2 = 8
8	8 - 0 = 8	8 + 2 = 10
