Kth Distinct String in an Array - Leetcode 2053 - In Hindi

In this video, we solve a string problem using Python and an efficient hashmap-based approach.
The task is to return the K-th distinct string—one that appears exactly once—from a list, in the order they appear.

👨‍💻 What you’ll learn:

- How to preserve order and identify distinct elements
- Efficient use of collections.Counter
- Optimizing string problems using hashmaps

🧠 Time Complexity Analysis:
🔸 Brute Force:
⏱️ O(n²) – For each element, we count its occurrences using a loop.

🔸 HashMap Approach:
⏱️ O(n) – One pass for counting, one pass to find the K-th distinct

📦 Space Complexity: O(n) – for storing frequencies
