Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value.

\n\n

If target is not found in the array, return [-1, -1].

\n\n

You must write an algorithm with O(log n) runtime complexity.

Example 1:

\n
Input: nums = [5,7,7,8,8,10], target = 8\nOutput: [3,4]\n

Example 2:

\n
Input: nums = [5,7,7,8,8,10], target = 6\nOutput: [-1,-1]\n

Example 3:

\n
Input: nums = [], target = 0\nOutput: [-1,-1]\n
