Java for LeetCode 153 Find Minimum 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 7
might become 4 5 6 7 0 1 2
).
Find the minimum element.
You may assume no duplicate exists in the array.
解题思路:
本题和Java for LeetCode 033 Search in Rotated Sorted Array题有点像,修改下代码即可,JAVA实现如下:
public int findMin(int[] nums) { int left = 0, right = nums.length - 1; while (left < right && nums[right] < nums[left]) { if (nums[(right + left) / 2] == nums[left]) return Math.min(nums[left], nums[right]); else if (nums[(right + left) / 2] > nums[left]) left = (right + left) / 2; else right = (right + left) / 2; } return nums[left]; }
