You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in the array. 链接:http://leetcode.com/problems/search-in-rotated-sorted-ar
}; 二:Search in Rotated Sorted Array Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 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 ...
Search in Rotated Sorted Array https://leetcode.com/problems/search-in-rotated-sorted-array/description/ Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums. You must write an algorithm with ...

退化版问题一:Search in Sorted Array 我们先从简单问题来考虑,假设这个数组并没有被 rotate 过,那么这道题就变成一道经典的在有序数组里查找一个元素的问题,其方法自然是 binary search。Binary search算法的核心要义在于我们每次可以排除掉数组里一半的元素,在剩余的另一半里继续寻找 target,并不断重复这个过程。
You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no duplicate exists in the array. 本题难度hard。利用二分查找法即可。分别使用迭代和递归实现。 【题意】 题目的意思是对rotated后的array,利用它的局部有序性来找到target,返回其...

LeetCode-33-搜索旋转排序数组(Search in Rotated Sorted Array)33. 搜索旋转排序数组整数数组 nums 按升序排列,数组中的值 互不相同。在传递给函数之前,nums 在预先未知的某个下标 k(0 <= k < nums.length)上进行了 旋转,使数组变为 [nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1...
33. Search in Rotated Sorted Array 题解 题目意思就是在一个上升序列中截断成AB 两个子序列 然后BA拼接成一个新的序列, 而题目要求 我们查找在这个序列中是否存在target,如果看到这里就会发现 这个很简单啊,查找一个序列中是否有某个数字 直接遍历就好了 方法木佬佬,但是 最重要的是题目末尾有一句 ...
sort that is theoretically optimal in terms of the total number of writes to the original array, unlike any other in-place sorting algorithm. It is based on the idea that the permutation to be sorted can be factored into cycles, which can individually be rotated to give a sorted result....
