题目: Given two sorted integer arrays A and B, merge B into A as one sorted array. Note: You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B a…

Given two sorted integer arrays A and B, merge B into A as one sorted array. Note:You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B are ma…

Given two sorted integer arrays A and B, merge B into A as one sorted array. Note:You may assume that A has enough space to hold additional elements from B. The number of elements initialized in A and B are m and n respectively. Summary: It's easy, b…

题目: Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 解题思路: 首先假设一个sorted没有rotated的数组[1,2,3],假设我们通过一个…

算法描述: Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example,Given input array…

题目: Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no du…

题目: There are two sorted arrays A and B of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 题解: 首先我们先明确什么是median,即中位数. 引用Wikipedia对中位数的定义: 计算有限个数的数据的中位数的方法是:把所有的同类数据按照大小的顺序排列…

这是悦乐书的第161次更新,第163篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第20题(顺位题号是88).给定两个排序的整数数组nums1和nums2,将nums2中的元素合并到nums1中,并且作为一个排序的数组.在nums1和nums2中初始化的元素个数分别为m和n.假设nums1有足够的空间(大于或等于m + n)来保存nums2中的其他元素.例如: 输入:nums1 = [1,2,3,0,0,0],m = 3,nums2 = [2,5,6],n = 3…

Given two sorted integer arrays A and B, merge B into A as one sorted array. Note:You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B are m …

Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note: The number of elements initialized in nums1and nums2 are m and n respectively. You may assume that nums1 has enough space (size that is greater or equa…
