Find the minimum element. You may assume no duplicate exists in the array. 这是LeetCode 上的一道算法题,题意是一个已经排序的数组,截断后重新拼接,找出数组中最小的数字。 这道题目用 Python 来实现的话太简单了。代码如下: classSolution:#@param num, a list of int
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. 代码:oj测试通过 Runtime: 52 ms 1classSolution:2#@param num, a list of in...

Leetcode Find Minimum in Rotated Sorted Array 题目大意: 对一个有序数组翻转, 就是随机取前K个数,移动到数组的后面,然后让你找出最小的那个数,注意,K有可能是0,也就是没有翻转。 毫无疑问,遍历一次肯定可以找到,但这样时间复杂度是O(n),如果你在面试的时候遇到这样的问题,你这样回答面试官肯定不会满意的...
This is a follow up problem to Find Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why? 分析 题目的意思是:给你一个排序的数组,但是现在我们从某个位置开始,把数组的后半部分搬到前面,这样构成的数组就是rotated sorted array。然后找出这个数组里面最小...

How you can apply your knowledge to the complementary task of finding minimum values Along the way, you’ve learned or refreshed your knowledge of the basics of NumPy syntax. NumPy is a hugely popular library because of its powerful support for array operations. Now that you’ve mastered the...
将思路扩展一下,在【leetcode-Python】- 二分搜索 - 153 Find Minimum in Rotated Sorted Array问题中,更新right = mid 其实也是让right暂存数组中可能的“第一个小于等于nums[-1]的元素”。随着搜索区间不断被收紧,直到left == right时,left或right的索引位置其实就是我们要的结果。
