273. Integer to English Words | Recursion | String | Leetcode Daily Challenge | DSA

In this video, I'll be solving the LeetCode problem titled "Integer to English Words" (Problem #273). This problem requires you to convert a non-negative integer into its English words representation. It's a great exercise for understanding how to break down and handle large numbers, and it involves concepts like array manipulation, string handling, and basic modular arithmetic.

I'll guide you through the process of converting any given number into its English words equivalent step-by-step. We'll start by breaking down the problem into smaller components, such as handling digits in the hundreds, thousands, millions, and billions places. I'll explain how to use arrays to store word representations for numbers and how to concatenate these words to form the final result.

This video covers:

Breaking down numbers into manageable parts (e.g., hundreds, thousands, millions).
Converting three-digit numbers into words.
Concatenating different parts to form the full word representation.
Handling special cases like zero.
Implementing the solution efficiently.
Example Walkthrough:
For example, given the number 1234567, we'll walk through the conversion to "One Million Two Hundred Thirty Four Thousand Five Hundred Sixty Seven", showing each step and explaining the logic behind the code.

Whether you're preparing for coding interviews, learning C programming, or simply interested in algorithmic challenges, this video will help you gain a solid understanding of number-to-words conversion and improve your problem-solving skills.
