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…

题目如下: 解题思路:题目要求时间复杂度是O(logN),可以尝试使用二分查找法.首先数组是有序的,而且仅有一个元素出现一次,其余均为两次.我们可以先找到数组最中间的元素,记为mid.如果mid和mid-1以及mid+1都不相同,那么mid就是single number.如果mid和mid-1相同,就要分两种情况,a.mid是奇数,single number会出现在mid的右半边:b.mid是偶数,出现在左半边.同理,如果mid和mid+1相同,那么是相反的:a.mid是奇数,出现在左半边:b.…
