88. Merge Sorted Array 这道题的trick在于如果从小到大排列的话,涉及到数组从左向右移动的问题。 所以这道题从大到小进行排序。 另外,这道题中该学习到的coding style,当需要处理2个数组/list时候 用 while (a != null && b != null) {} while (a != null) {} while (b != null) {} 这样3个...
Solution 2 The key to solve this problem is moving element of A and B backwards. If B has some elements left after A is done, also need to handle that case. Time complexity O(n), space cost O(1) 1publicclassSolution {2publicvoidmerge(int[] nums1,intm,int[] nums2,intn) {3whil...
Merge Sorted Array - LeetCode (如有侵权,请联系作者删除) Easy 题意 给定两个有序数组,需要将这两个数组内的元素归并在一起。但是不能申请额外的空间,要写成一个build-in的方法,最后所有的元素全部存在nums1这个vector当中 题解 这题相信大多数人一眼就可以看出来是一个归并,但问题是我们不能创建多余的数组...
Can you solve this real interview question? Merge Sorted Array - You are given two integer arrays nums1 and nums2, sorted in non-decreasing order, and two integers m and n, representing the number of elements in nums1 and nums2 respectively. Merge nums1
problem Merge Sorted Array code class Solution { public: void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) { int i=m-1, j=n-1, tar=m+n-1; while(j>=0) { nums1[tar--] = (i>=0&&nums1[i]>nums2[j]) ? nums1[i--] : nums2[j--]; ...
Merge two given sorted integer array A and B into a new sorted integer array. 合并两个排序的整数数组A和B变成一个新的数组。 【题目链接】 http://www.lintcode.com/en/problem/merge-two-sorted-arrays/ 【题目解析】 A和B都已经是排好序的数组,我们只需要从后往前比较就可以了。
88. Merge Sorted Array Given two sorted integer arraysnums1andnums2, mergenums2intonums1as one sorted array. Note: The number of elements initialized innums1andnums2aremandnrespectively. You may assume thatnums1has enough space (size that is greater or equal tom+n) to hold additional elemen...
Also, the resulting array contains all the elements sorted in the ascending order, similarly to the arrays and . Now that we reached a good understanding of the problem, let’s dive into the solutions. 3. Naive Approach Let’s discuss the naive approach firstly. After that, we can see ho...
For each array run read from the input file, ensure that no more than 'run_size' elements are read at once. Sort the run using MergeSort. Save sorted array into a designated file, denoted as 'i' for the respective file. Combine sorted files with sorted arrays utilizing the discussed met...
The merge_sort function sorts the array in ascending order. The sort_ascending and sort_descending functions use merge_sort to sort the array in ascending and descending order, respectively. $ ./merge_sort.py Sorted numbers (ascending): [3, 9, 10, 27, 38, 43, 82] Sorted numbers (...
