和上题一样,这里要求可以重复数字。那么需要考虑的就比较多一步了。如果中间的值和左边的值相等的话,并且中间下标不等于左边下标的话,那么就存在问题了,因为我们不知道最小的到底会出现在哪里。那么就只能left++,继续判断了,所以最坏情况还是O(n)只要在上题基础上,稍微修改一下就行了。class Sol...

一个有序数组,没有重复数字,向右推进了几次,找出最小值。例如(i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2).直接遍历一次找到答案就没有意义了。之前做过类似的题目,不过我找不到具体的题号了。所以就随便搜了下Garnker的,知道是Search in Rota...
