Given an array of integers nums
sorted in ascending order, find the starting and ending position of a given target
value.
Your algorithm’s runtime complexity must be in the order of O(log n).
If the target is not found in the array, return [-1, -1]
.
Example 1:
Input: nums = [5,7,7,8,8,10]
, target = 8
Output: [3,4]
Example 2:
Input: nums = [5,7,7,8,8,10]
, target = 6
Output: [-1,-1]
可以直接使用二分查找,搜索两次。
