The array may contain duplicates. 详见Leetcode Analysis Find Minimum in Rotated Sorted Array 因为题目给出的序列是相对有序,所以我们依然可以采用二分搜索的方式来查找。首先判断当前中间的那个元素是否比我们现在所拥有的最小值小,如果是这样的话,更新最小值。然后判断现在搜索区间的中心元素是否比最后一个元素...
This is a follow up problem toFind Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why? 如果采用153的上面那种解法,在二分里面找turning point return的话,因为上一题最后return的时候直接无脑return nums[0],但这一题就不太行了,所以最好还是把它拎出来...
This is a follow up problem to Find Minimum in Rotated Sorted Array. Would allow duplicates affect the run-time complexity? How and why? 描述 假设按照升序排序的数组在预先未知的某个点上进行了旋转。 ( 例如,数组 [0,1,2,4,5,6,7] 可能变为 [4,5,6,7,0,1,2] )。
