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. 做完了Find Minimum in Rotated Sorted Array之后,对这题又发现了一种非常简单的
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).Find the minimum element.You may assume no duplicate exists in the array. 这道题和原题的唯一区别在于我们不需要找任意 target,而只需要...
Search in Rotated Sorted Array I 要搜索的对象是一个rotated sorted array,所以从直觉上时间复杂度应该不会超过O(logn)。解决这个题目的另一个思路就是先把pivot找出来,在这里我把pivot定义为数组中最小的那个数。所以下面要解决的便是能不能在O(logn)的时间找到pivot。沿着这个思路,然后综合rotated sorted ar...
publicintsearch(int[]nums,inttarget){intstart=0;intend=nums.length-1;//找出最小值的数组下标/* while (start < end) {int mid = (start + end) / 2;if (nums[mid] > nums[end]) {start = mid + 1 ;} else {end = mid;}}int bias = start;*///找出最大值的数组下标while(start<end...
Leetcode 33. Search in Rotated Sorted Array Search in Rotated Sorted Array 题目大意:给定一个有序数组,经过旋转得到新得数组,也即改变起点位置,如[0,1,2,4,5,6,7] 变成[4,5,6,7,0,1,2]。要求仍然在log的时间进行查找某个特定的target...
33. Search in Rotated Sorted Array I & II 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....
This algorithm is a combination of radix sort and quicksort. Pick an element from the array (the pivot) and consider the first character (key) of the string (multikey). Partition the remaining elements into three sets: those whose corresponding character is less than, equal to, and greater...
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 ...
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...
