( mergeSort(int[] A) (接受一个数组的输入)和合并( int[] a、int[] l、int[]r)的布局相同。主要问题是将Arrays.copyOfRange转换为非-package版本的java到此代码。谢谢你回答这个问题。这种方法不像Arrays.copyOfRange那样快，也不包括所有的情况，如负索引，也有必要检查大小。为一次数
const mergeSort = array => { if (array.length < 2) { //function stop here return array } const middle = Math.floor(array.length / 2); const leftSide = array.slice(0, middle); const rightSide = array.slice(middle, array.length); return merge(mergeSort(leftSide), mergeSort(right...
基于迭代的归并排序算法 (i.e. Bottom-up mergesort) 基于递归的归并排序算法 (i.e. Top-down mergesort) 基于迭代的归并排序算法(Bottom-up mergesort) 假设初始对象序列有n个对象,首先将其看做是n个长度为1的有序子序列,先做两两归并,得到(n+1)/2个长度为2的归并子序列(如果n为奇数,则最后一个有序...
But Merge Sort can also be implemented without the use of recursion, so that there is no function calling itself.Take a look at the Merge Sort implementation below, that does not use recursion:Example def merge(left, right): result = [] i = j = 0 while i < len(left) and j < ...
二、recursion 递归方法是在disuss上看到的,原文:Java, 1 ms, 4 lines codes, using recursion (依然是为华人写的,再次展现中国人在算法方面的才华) public ListNode mergeTwoLists(ListNode l1, ListNode l2){ if(l1 == null) return l2; ...
