Search in Rotated Sorted Array I && II Leetcode 对有序数组进行二分查找(下面仅以非递减数组为例): 1. int binarySort(int A[], int lo, int hi, int target) 2. { 3. while(lo <= hi) 4. { 5. int mid = lo + (hi - lo)/2; ...
33. Search in Rotated Sorted Array 假设按照升序排序的数组在预先未知的某个点上进行了旋转。 ( 例如,数组 [0,1,2,4,5,6,7] 可能变为 [4,5,6,7,0,1,2] )。 搜索一个给定的目标值,如果数组中存在这个目标值,则返回它的索引,否则返回 -1 。

leetcode 33 Search in Rotated Sorted Array 详细解答 因为题目要求时间复杂度要是O(log n),所以这里很明显要用二分法。 但应该怎么构造二分? 流程如下: 具体代码如下:智能推荐leetcode 33[medium]---Search in Rotated Sorted Array 难度:medium Suppose an array sorted in ascending order is rotated at...
There is an integer array nums sorted in ascending order (with distinct values). 一个升序排序的整数数组 Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is [nums[k], nums[k+1], ......
