Binary Search Questions Series - Find first and last position of element in sorted array leetcode
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 O(log n) runtime complexity.
Example 1:
Input: nums = [5,7,7,8,8,10], target = 8
Output: [3,4]
Example 2:
Input: nums = [5,7,7,8,8,10], target = 6
Output: [-1,-1]
Example 3:
Input: nums = [], target = 0
Output: [-1,-1]

Code With Ease is meant to make problem-solving in programming easier. For DSA preparation, we post topic-specific videos pertaining to Coding Interview topics so that everyone may approach such questions with a clear thought process and achieve the best outcomes. In addition, we make an effort to include different "Primer Series" that teach particular concepts or algorithms. We want to be the one-stop solution for everything pertaining to DSA preparation and programming foundations in general, saving candidates from having to visit many sources in order to receive structured content.
Additionally, we believe that learning to code entails much more than only "cracking the coding interview." The long-term goal of this channel is to create more proficient problem-solvers in this field so that, in the end, we can create fantastic products and be able to resolve challenging issues in our environment to improve the quality of life for everyone.
