Solution: Find First and Last Position of Element in Sorted Array
Explore how to efficiently locate the first and last occurrences of a target value in a sorted integer array by applying a modified binary search. Understand how to implement a helper function that finds boundary positions while maintaining logarithmic runtime. This lesson helps develop skills to handle search problems using binary search variations with optimal time and constant space complexity.

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
