所以就随便搜了下Garnker的,知道是Search in Rotated Sorted Array,那题是找目标值。这里是找最小值。 我是这样想的,分为几部分, 1.如果左边的值等于中间的值了,那么就剩下两个数要判断了,而且是相邻的。 2.如果中间的值大于左边的值,那么最小值肯定不是在最左边就只在右边一块了。 3.如果中间值小于左...
一、题目描述 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). Find the minimum element. You may assume no duplicate exists in the array. 二、分析 这题难度有,因为他默认的是数组中所有的元素是不同的。只...
Can you solve this real interview question? Find Minimum in Rotated Sorted Array - Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become: * [4,5,6,7,0,1,2] if
Suppose a sorted array is rotated at some pivot unknown to you beforehand. 0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 思路: 有序数组旋转后,如果mid元素比low大,则左边有序,右边乱序,考虑最左元素是否最小元素...
Find Minimum in Rotated Sorted Array -- LeetCode 这道题是Search in Rotated Sorted Array的扩展,差别就是如今不是找一个目标值了,而是在bst中找最小的元素。主要思路还是跟Search in Rotated Sorted Array差点儿相同。还是通过左边界和中间的大小关系来得到左边或者右边有序的信息。假设左半边有序。那么左...
