Given an array nums, return true if the array was originally sorted in non-decreasing order, then rotated some number of positions (including zero). Otherwise, return false. There may be duplicates in the original array. Note: An array A rotated by x positions results in an array B of ...
Input:nums = [2,1,3,4]Output:falseExplanation:There is no sorted array once rotated that can make nums. Example 3: Input:nums = [1,2,3]Output:trueExplanation:[1,2,3] is the original sorted array. You can rotate the array by x = 0 positions (i.e. no rotation) to make nums....
Amajority elementis an element that appears more thanN/2times in an array of lengthN. Example 1: Input: nums =[2,4,5,5,5,5,5,6,6], target =5 Output:true Explanation: The value 5 appears 5 times and the length of the array is 9. Thus, 5 is a majority element because 5 > ...

For example, given array S = {-1 2 1 -4}, and target = 1. The sum that is closest to the target is 2. (-1 + 2 + 1 = 2). 分析:本题与上一题相似,仅仅是求解目标不同,但仅仅涉及到搜索,而没有查重过程。 初解:设置三重循环分别用于搜索a,b,c三个变量的可能值,然后比较求和结果与...
Suppose an array sorted in ascending order 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, otherwis...
The array is only modifiable by the update function. You may assume the number of calls to update and sumRange function is distributed evenly. 【解答】写的代码看起来有点啰嗦,大致思路是线段树。也就是说,每个节点都存放一个 sum,这样在求一段区间的和的时候会比较快;而在更新某一个数...
Given a sorted array of integers, find the starting and ending position of a given target value. Your algorithm’s runtime complexity must be in the order of O(log n). If the target is not found in the array, return[-1, -1]. ...
