Puzzle C/5 about the spider and fly has wrong answer.

(23^2 + 26^2)^0.5 = 34.71

But the fact is that not only the answer for equation is wrong, also the path is not the shortest one!

The spider can walk through wall but very close to the floor to reach for fly,

and the path will be: 15 + e + 18 + e = 33 + 2e

e can be any real number greater than zero (In case e = 0 spider will touch floor)

and we can see 33.0.... is less than 34.71.

Also puzzle J4 answer is 2 * (1/256) ^ 2 + 2 * (8/256) ^ 2 + 2 * (28 / 256) ^ 2 + 2 * (56 / 256) ^ 2 + (70/256) ^ 2 = 0.19638
