95. “A” futbol klubining 30 ta o’yinda to’plagan ochkolari quyidagi ko’rinishda faylda yozilgan:
3 0 0 0 0 1 0 0 0 3 0 0 3 3 3 3 3 1 1 1 0 0 0 0 0 0 0 3 3 3 …
3 – g’alaba
1 – during
0 – mag’lubiyat.
Quyidagilarni aniqlash uchun sinf hosil qiling:
1) Jamoaning umumiy ochkosini aniqlash metodi
2) Jami g’alabalar sonini aniqlash metodi
3) Jami duranglar sonini aniqlash metodi
4) Jami mag’lubiyatlar sonini aniqlash metodi
