Quyidagi algoritm natijasini toping. A) 2 B) -1 C) 3 D) 0 11 / 30 11. Quyidagi algoritm natijasini toping. A) 11 B) 81 C) 9 D) 6 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 Endi A > 9 sharti haqiqat bo‘ldi (10 > 9).Shu paytda S ning qiymati: 8.
