📌 Problem: 443: String Compression | LeetCode 75 | Python Solution
In this video, I walk you through solving the "String Compression" problem from LeetCode 75. This is a fundamental string manipulation problem perfect for beginners learning Python and preparing for coding interviews.
🎯 What You'll Learn:
✅ String manipulation techniques in Python
✅ Two Pointers
✅ Time and space complexity analysis
✅ Clean, optimized Python code
✅ Edge case handling
💻 Problem Description:
Given an array of characters `chars`, compress it using the following algorithm:
Begin with an empty string `s`. For each group of *consecutive repeating characters* in `chars`:
If the group's length is `1`, append the character to `s`.
Otherwise, append the character followed by the group's length.
The compressed string `s` **should not be returned separately**, but instead, be stored **in the input character array `chars`**. Note that group lengths that are `10` or longer will be split into multiple characters in `chars`.
📚 Difficulty: Medium
🏷️ Topics: 2 Pointers, Array
