Musiyano Pakati peKuputika-Chiratidzo Chikamu AT BT CT

Chekutanga, ese matatu maturusi akagadzirirwa kudzivirira kuputika kweguruva uye anowira pasi pechikamu chechipiri chekuputika-proof michina. Izvo zvinoputika-zvisingabvumirwe zviyero zvinotevera: AT < BT < CT.

Zvishandiso zveCT zvinoratidzira chiyero chepamusoro cheguruva uye chinogona kushandiswa munzvimbo dzakarongedzerwa AT neBT.. Zvisinei, AT uye BT zvishandiso hazvina kukodzera nzvimbo dzinoda CT zviyero.

Nemamwe mashoko, CT zvishandiso zvinogona kutsiva AT uye BT, asi AT neBT zvishandiso hazvigone kutsiva CT.
