3330. Find the Original Typed String I | Leetcode | Python in Tamil | Soumil Speaks

Welcome back to Soumil Speaks! In this video, we solve an interesting string simulation problem — how to reconstruct the original string from a version where some characters were possibly held down (typed multiple times).

This is a great problem to build your understanding of pointer-based string traversal, and how to handle real-world typing logic in code!

🎯 What you’ll learn:

What the problem means in simple Tamil

How to compare two strings with different typing styles

Logic using two pointers

Step-by-step Python implementation

Interview-style dry-run walkthrough

Edge cases and optimizations

📌 Language: Tamil
📌 Difficulty: Easy
📌 Leetcode Problem: 3330
📌 Best For: Beginners, string logic practice, and interview starters

🧠 Quick Logic Overview:

Traverse both strings using two pointers

Allow characters in the typed string to repeat

But ensure all characters of the original string appear in correct order

If traversal completes successfully: it's valid
