Search for a Range

Question 1

Search for a Range

• Given an array of integers 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].
• For example, Given [5, 7, 7, 8, 8, 10] and target value 8, return [3, 4].
