将顺序表重新排列成以第一个元素为界的两部分，前一部分元素的值都小于它，后一部分元素的值都大于或等于它。估算所设计算法的时间复杂度和空间复杂度-Will be re-arranged in the order form the first element is bounded by the two parts, the first part of the element values are less than it, and the latter part of the element values are greater than or equal to it. Designed to estimate the time complexity and space complexity
