Solution: Find First and Last Position of Element in Sorted Array
Understand how to apply a modified binary search technique to find the first and last positions of a target value in a sorted array efficiently. This lesson guides you through implementing a helper function to search boundaries, ensuring a logarithmic runtime while handling cases where the target is absent.

Statement
You are given an integer array, nums, that is sorted in non-decreasing order. Your task is to find the first and last indexes of a given value, target, within this array.
If the target does not appear in the array at all, return [-1, -1].
Note: You must write an algorithm with
