思路：① 算每辆车到达时间 = (target - position) / speed；② 按位置降序排序；③ 单调递增栈：仅当当前时间 栈顶时间时压栈（新车队），否则合并。栈长即为车队数。可优化为用变量代替栈。
春节出游，我最推荐大家尝试「鲜艳」，能很好地还原春节集市上那些复杂的色彩，红色的对联、金色的福字、五彩的糖果，在 XMAGE 的加持下，会呈现出一种油润且厚重的质感，非常适合表现「热闹」这个主题。

The N-closest or N-best dithering algorithm is a straightforward solution to the N-candidate problem. As the name suggests, the set of candidates is given by the closest palette colours to the input pixel. To determine their weights, we simply take the inverse of the distance to the input pixel. This is essentially the inverse distance weighting (IDW) method for multivariate interpolation, also known as Shepard’s method. The following pseudocode sketches out a possible implementation:，更多细节参见WPS下载最新地址
