}
return result /2;
}
else
{
return result *3;
}
}

{
if (a==0)
{
if (b==0)
{
return result *2;
}
return result /2;
}
else
{
return result *3;
}
}

Explanation / Answer
1. if string str = "Grand Canyon", then what is the value of str.substring (7);-----B) anyon
substring method skips characters until given index and gives rest of characters.
2.x=total (1,0,1)------E) x being assigned the value 0
result (1)/2=0.5 but return type is integer ,So total function return 0.
3. x=total (5,0,0)-------E) x being assigned the value 10
result (5)*2=10; return type is integer and 10 is also an integer.
