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 = [1,1,1]Output:trueExplanation:[1,1,1] is the original sorted array. You can rotate any number of positions to make nums. Example 5: Input:nums = [2,1]Output:trueExplanation:[1,2] is the original sorted array. You can rotate the array by x = 5 positions to begin ...
Given an arraynumssorted in non-decreasing order, and a numbertarget, returnTrueif and only iftargetis a majority element. 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 E...
Given an array of integers that is alreadysorted in ascending order, find two numbers such that they add up to a specific target number. The function twoSum should return indices of the two numbers such that they add up to the target, where index1 must be less than index2. Please note ...

167.two-sum-ii-input-array-is-sorted 给定一个已按照升序排列 的有序数组,找到两个数使得它们相加之和等于目标数。 函数应该返回这两个下标值 index1 和 index2,其中 index1 必须小于 index2。 说明: 返回的下标值(index1 和 index2)不是从零开始的。
arr = list(np.array(range(n))) get_ranks(arr) 题目三 给出一个递增数组arr,存在重复的数字,给出一个目标数字tar,找出该数字在数组中出现的位置区间,如果不存在则返回-1,-1,如果存在返回区间如2,3 def get_interval(b, e, inputs, tar): ...
题目: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, otherwise return -1.You may assume no dupli...
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...
