There are three switches $A, B$ and $C$ which can be in $ON/OFF$ position. Their settings change as per the following rules:

i) If $A$ is the only switch as $ON$ , change $B$ to $ON$ .

ii) If $A$ and $B$ are only switches as $ON$ , change $C$ to $ON$ .

iii) If all three switches are $ON$ , change $C$ to $OFF$ .

iv) For all other situations, all switches in $ON$ are changed to $OFF$ and all switches in $OFF$ are changed to $ON$ .
