假设一个按照升序排列的有序数组从某未知的位置旋转.(比如 0 1 2 4 5 6 7 可能变成 4 5 6 7 0 1 2).找到其中最小的元素.你可以假设数组中不存在重复的元素.详见:https://leetcode.com/problems/find-minimum-in-rotated-sorted-array/description/ Java实现: class Solution { public int findMin(int[] nums) { int low=0; int high…

这4个题都是针对旋转的排序数组.其中153.154是在旋转的排序数组中找最小值,33.81是在旋转的排序数组中找一个固定的值.且153和33都是没有重复数值的数组,154.81都是针对各自问题的版本1增加了有重复数值的限制条件. 153.154都需要考虑是否旋转成和原数组一样的情况,特别的,154题还需要考虑10111和11101这种特殊情况无法使用二分查找. 33.81则不用考虑这些情况. 找最小值的题主要是利用最小值小于他前一个位置的数,同时也小于后一个位置的数 153. Find Mini…

Question 153. Find Minimum in Rotated Sorted Array Solution 题目大意:给一个按增序排列的数组,其中有一段错位了[1,2,3,4,5,6]变成[4,5,6,1,2,3],把1求出来 思路:遍历,如果当前元素比前一个元素小就是这个元素了 Java实现: public int findMin(int[] nums) { int ans = nums[0]; for (int i=0; i<nums.length; i++) { int pre…

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. Example 1: Input: [3,4,5…
