33. Search in Rotated Sorted Array # 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 arr
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; 6. if(A[mid] == target) 7. return mid; 8....
You may assume no duplicate exists in the array. Tag: Array; Binary Search 体会: 这道题和Find the Minimum In Rotated Sorted Array肯定是有联系啦,毕竟给的都是Rotated Sorted Array这种结构。思路是:从middle处开始左右两部分,一部分是sorted的了,另一部分rotated或者sorted。我们要去分析sorted的那个部分。
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. ...
81. Search in Rotated Sorted Array II https://leetcode.com/problems/search-in-rotated-sorted-array-ii/ 这两道题都是属于循环有序数组的查找问题,无论是查找具体元素的下标还是检查一个目标值是否在数组中,主要的判断逻辑都是一致的。

进阶习题-题目选自leetcode-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 。 你可以假设数组中不存在重...
1. Search in Rotated Sorted Array(33.leetcode) 当 选择 right= nums.length -1 时, while loop 的终止 会是 left < right , 而不是 while(left <= right) 解题思路:只找 连续 increasing 的区间, publicintsearch(int[]nums,int target){intleft=0,right=nums.length-1;while(left<right){int ...
