Welcome to Day 17 of the 150 Days Coding Challenge, where we solve LeetCode problems with efficient solutions. In this live session, we will tackle LeetCode – Height Checker, a commonly asked problem in Google, Microsoft, Apple, Bloomberg, Facebook (Meta), and other top tech company interviews. This session will help you strengthen your Data Structures and Algorithms (DSA) skills and improve your coding interview preparation.

📌 Problem Statement - Height Checker (LeetCode)
Given an array heights representing the heights of students standing in a line, return the number of students who are not in their correct positions when sorted in non-decreasing order. A student’s position is incorrect if their height does not match the expected height in the sorted order.

🎯 Topics Covered in This Live Session:
✅ LeetCode 1051 Height Checker problem statement & explanation
✅ Sorting technique to compare the original vs. sorted array
✅ Optimal approach with Time & Space Complexity analysis
✅ Edge cases & variations of the problem asked in FAANG interviews
✅ Live coding in Python & Java with step-by-step explanation
