* Solution:
* 考虑边界,推导结论,子问题递归求解
如果 S <= p[1] 或者 S >= p[n] ,显然所有人投票都是一个方向,不妨假设 p[1] < S < p[n] 。
考虑处在最边上的 1 号点和 n 号点,如果 a[1] >= a[n] ,那么一定先到 1 ,否则先到 n 。归
纳证明,如果 n = 2 显然成立,对于 n >= 3 ,若 S >= a[n - 1] 显然成立,否则 S < a[n - 1] ,
此时考虑 1 和 n - 1 ,如果先到 n - 1 就会回到 S >= a[n - 1] 的情况。
不妨假设 a[1] >= a[n] ,那么到 n 的时间就一定是到 1 的时间加上 1 到 n 的距离,那么 n 想
要最小化到达 n 的时间其实就是等价于最小化到达 1 的时间,可以赋值 a[1] = a[1] + a[n] 并赋
值 n = n - 1 转换为子问题,递归求解,可以求出每个点的到达时间。
