first of all,the type of balance must be clearified
if the balance is a modern one then the former solutions
can be working
else
we have to start with 1 jar on one side and 1 on the other
hand of the balance.
if the needle is in cente then ok or we will find the
required jar
else
put the second and third jar on the sides and now if the
neddle is again in centre then the remaining one is
contaminated otherwise the side where the needle goes down
has the right jar and opposite side has required jar(3 or 4)
