Dutch National Flag Algorithm Explained in Telugu | Leetcode Q75 Sort Colors | Python DSA | srkcodes
6Welcome to srkcodes, your go-to channel for Telugu coding tutorials, Leetcode solutions, and Python programming for interviews! In today’s video, we’ll dive deep into the Dutch National Flag Algorithm and solve Leetcode Question #75: Sort Colors, a crucial problem for DSA preparation and coding interviews.
This video breaks down the algorithm in Telugu to help you understand the sorting logic with both brute force and optimal approaches. The Dutch National Flag Algorithm is widely used in interview questions for Python programming and helps build a strong foundation in DSA for job interviews.
🔍 What You’ll Learn:
1️ ⃣ Brute Force Approach (O(N) Time, O(N) Space):
Count the number of zeros, ones, and twos using lists.
Reconstruct the array based on these counts.
2️ ⃣ Dutch National Flag Algorithm (O(N) Time, O(1) Space):
Learn how to use three pointers: low, mid, and high.
Solve the problem efficiently while optimizing space complexity.
3️ ⃣ Practical Python Implementation:
Step-by-step coding in Python with clear explanations in Telugu.
Time complexity and space complexity analysis for both methods.
