This article mainly introduces the JavaScript to achieve a given radius of the circle of the relevant data, the need for friends can refer to the The code is quite simple, here is not much nonsense, small partners to their own reference under it. ? 1 2 3 4 5 6 The above mentioned is the entire content of this article, I hope you can enjoy.

The competition of the electric circle is being known by many people, many stationmaster also began to join the battle, in this game in full swing, many sites will experience the exclusion of many sites, that is, my site is sure to put your station squeezed down, so there is a problem, new station and old station problem, new station momentum full, The old station is basically stable. The new station is always trying to squeeze forward, and the old st

problem Description You are been given a circle from 0 to n-1. If you is currently at x, you'll move to (x-1) mod n or (x + 1) mod n with equal probability. Now we want to know the expected number of steps you need to reach X from 0. Input The first line contains one integer t-the number of test cases. Each of the next T lines contains, integers n, x (0≤x Output For each test case. Print a single float number-the expected number of steps you need to
