LeetCode 806: Number of Lines To Write String — The String Trick (C#)

In this video, we break down LeetCode problem 806: Number of Lines To Write String. Perfect for absolute beginners in Data Structures and Algorithms, we explain how to calculate how many lines of text fit on a page with a fixed width. We start from scratch, defining the problem using a real-world analogy of writing on lined paper. You will learn why a naive approach might seem logical but fails to be efficient, and then we reveal the optimal single-pass strategy. We walk through every single line of the logic, explaining exactly how we track current width and line count without writing a single line of code in the narration. By the end, you will understand how to solve this using a simple linear scan, mastering the concept of state tracking. This is the perfect introduction to array manipulation and string processing patterns.
