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...

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 ...
