递归的最底层 quick sort:只有3个元素,中间的元素是分界值,把比它小的那个元素搬到左边,比它大的元素搬到右边,排序完成。 分区函数的思想: 抽出第一个元素,然后从列表最右端的元素开始,寻找比第一个元素更小的元素,搬到左边(=第一个元素的不移动); 从左边第一个元素开始(包括了第一个元素),寻找比第一个元素更大的元素,搬到右边(=第一

First, the Multi-Deque Partition Dual-Deque Merge Sort function, MPDMSort, is the main function for partitioning and sorting, as shown in Algorithm 1. The median of five function (MedianOf5) is the algorithm for selecting pivot (Algorithm 2). The InitBlocks function (Algorithm 3) is...
Alignment of an ultra-long ONT read from a chromothriptic region. Mapping coordinates in the entire human reference genome (y-axis) in function of the position in the read, showing where sub-sequences of the chimeric read map in the genome for (a)single-idx, (b)part-idx-no-merge, and...
