Use a while-loop to find the smallest
positive integer $n$, such that $\sqrt{n}-\sqrt{n-1}<0.01$.
Remember that $\sqrt{something}$ in Lua is math.sqrt(something).
What is your answer? a) 2499 b) 2500 c) 2501 or d) 10,000 e) there is no such integer. (From Artino, 1978, #18.)
Now you try. Fix the while loop to stop when d becomes less than 0.01, and fix
the d= line to compute $\sqrt{n}-\sqrt{n-1}<0.01$.
