如果我们不用这种方法,那么我们需要更加深入地去判断每种可能出现地情况。 当nums[mid] > nums[start] 和 nums[mid] < nums[end] 都不满足时,则: numd[start] <= nums[mid] 并且 nums[mid] >= nums[end] 如果我们再仔细想,由于数组旋转之前整体有序,那么旋转之后得到的两条线段本身应该是有序的,而且...
此题是Search in Rotated Sorted Array的加强版,将一个有序数组往右移动若干位。这里的有序数组允许有重复数字。 如果没有重复数字,那么复杂度是O(logn),用二分查找,根据中间值和左右两边的大小,以及和target的大小,来判断缩小一半查找。 但是出现重复数字之后,如果中间值和左右两边的值相等,我们就不知道如何切除...
