19. Length of Last Word – LeetCode 58 ✍️ 2 Clean Approaches | Forward Scan vs Backward Scan

In this video, we solve LeetCode 58 – Length of Last Word, a simple-looking problem that actually tests string traversal, edge cases, and clean thinking — exactly what interviewers look for.

We cover 2 elegant approaches:
✅ Approach 1: Forward Scan
✅ Approach 2: Backward Scan (Most Optimal)

You’ll learn:
How to handle trailing spaces correctly
How to write bug-free string logic
Why backward scanning is often preferred in interviews

This is part of my LeetCode Top Interview 150 Series, where we solve problems with multiple approaches + interview clarity.
