Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. If target is not found in the array, return [-1, -1]. You must write an algorithm with 0(log n) runtime complexity.

Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value.
If target is not found in the array, return [-1, -1].
You must write an algorithm with 0(log n) runtime complexity.
Example 1:
Input: nums = [5,7,7,8,8,10], target = 8
Output: [3,4]
Example 2:
Input: nums = [5,7,7,8,8,101, target = 6
Output: [-1,-1]
Example 3:
Input: nuns = [], target = 0
Output: [-1,-1]
Constraints:
• 0 <= nums.length <= 10³
-109 <= nums [1] <= 10⁹
nums is a non-decreasing array.
.
• -109 < target <= 109
