Question: Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Analysis: 1)两个都是空串: 2)一个是空串: 3)新建一个伪头结点,用于新串的连接: 4)最后还要检查是否有一个串还有数字. Answer: public ListNode merge…

归并排序(Merge Sort)与快速排序思想类似:将待排序数据分成两部分,继续将两个子部分进行递归的归并排序:然后将已经有序的两个子部分进行合并,最终完成排序.其时间复杂度与快速排序均为O(nlogn),但是归并排序除了递归调用间接使用了辅助空间栈,还需要额外的O(n)空间进行临时存储.从此角度归并排序略逊于快速排序,但是归并排序是一种稳定的排序算法,快速排序则不然. 所谓稳定排序,表示对于具有相同值的多个元素,其间的先后顺序保持不变.对于基本数据类型而言,一个排序算法是否稳定,影响很小,但是…

M erge sort is based on the divide-and-conquer paradigm. Its worst-case running time has a lower order of growththan insertion sort. Since we are dealing with subproblems, we state each subproblem as sorting a subarray A[p .. r].Initially, p = 1 and…

Description You know sorting is very important. And this easy problem is: Given you an array with N non-negative integers which are smaller than 10,000,000, you have to sort this array. Sorting means that integer with smaller value presents first. In…
