最大间隙问题：给定n 个实数x , x , , xn 1 2  ，求这n 个数在实轴上相邻2 个数之间的最

大差值。假设对任何实数的下取整函数耗时O(1)，设计解最大间隙问题的线性时间算法。-The maximum gap problem: given n real numbers x, x, xn 1 2  , seeking the n numbers adjacent to the maximum difference between the two numbers on the real axis. Assuming rounding function for any real numbers under consuming O (1), linear-time algorithm design solution maximum gap problem.
