As of September 10, 2014, the srm system of the orling plant had been operating stably for nearly eight years. There were 2174 System Management suppliers and 1409 account users, resulting in a total of nearly 100 GB of business data, nearly 0.15 billion pieces of core business data are generated, and more than 80 thousand piece

The formula is simple.
N * (1/n + 1/(n1) + 1/(n2) +... + 1/(nk + 1 ))
The key issue is coming.
N and K are huge.
Then we found that this is a harmonic series sum.
When the number is large, only the approximate formula is used.
Try it.
(1/n + 1/(n1) + 1/(n2) +... + 1/(nk + 1) is approximately equal to log (n + 1) + R

Question: Give a vertex (x, y), give some step delta1, delta2... deltan: Can I reach the (x, y) point after completing n steps in strict accordance with the step (0, 0.
Solution: in fact, it is to determine whether these line segments and (0, 0)(x, y) can constitute a multilateral (angle ?) You only need to judge whether the longest side is less than half of the length of all sides.
