If you want to practice data structure and algorithm programs, you can go through100+ java coding interview questions. In this post, we will see about Sorting algorithms in java. A Sorting algorithm is an algorithm which puts collection of elements in specific order. For example: You want to...
Quicksort is similar to MergeSort in that the sort is accomplished by dividing the array into two partitions and then sorting each partition recursively. In Quicksort, the array is partitioned by placing all items smaller than some pivot item before that item and all items larger than the piv...
Sorting is arranging elements in an ordered sequence. Over the years, several algorithms were developed to perform sorting on data; for instance merge sort, quick sort, selection sort, or bubble sort. (Another meaning of sorting is categorizing: grouping elements with similar properties.) The oppo...

Algorithms 若数据能够放入内存中,我们可以使用标准排序算法搞定,如快排;若数据无法放入内存中,就得考虑数据在 disk 与 memory 中移动的成本,以及排序算法的适配。 External Merge Sort 外部排序通常有两个步骤: Sorting Phase:将数据分成多个 chunks,每个 chunk 可以完全读入到 memory 中,在 memory 中排好序后再写...
Why java.util.Arrays uses Two Sorting Algorithmsjava.util.Arrays uses quicksort (actually dual pivot quicksort in the most recent version) for primitive types such as int and mergesort for objects that implement Comparable or use a Comparator. Why the difference? Why not pick one...
This chapter provides tutorial notes and codes on Perl implmentations of different sorting algorithms: Bubble Sort, Heap Sort, Insertion Sort, Merge Sort, Quicksort, Selection Sort, and Shell Sort.
