Dr. Tanzil's Island

Limits 1s, 512 MB

Dr Tanzil has a circular shaped lake that he bought long ago. One day while he was visiting there, he found out with great surprise that, there has risen a round shaped island exactly from the center of the lake. He was very happy and considered the island as a gift from God. He decided to use the island for the welfare of people. So he decided to build a library that would be open for everyone.
