原题地址跟Find Minimum in Rotated Array类似，折半查找将A平均分成两半A[l..m]和A[m+1..r]如果target可能出现在A[l..m]，则保留A[l..m]，去掉A[m+1..r]反之，保留A[m+1..r]，去掉A[l..m]。根据区间的连续性判断target...

原题地址说个题外话，我一直想不明白题目里rotate这个词，感觉用shift更合适啊仔细分析题目，有如下两个性质：1. 对于一个没有折叠过的数组，最小值一定是第一个元素。2. 对于一个折叠过的数组，最小值一定出现在折叠的地方。因此，要找最小值，就把以上两种情况下的最小值都看看，选一个最小的就行了。这...

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 ...
