Udemy – Python Data Structures & Algorithms: Visual DSA + LeetCode

Welcome to Python Data Structures & Algorithms: Visual DSA + LeetCode, a comprehensive, animation-driven course designed to help you understand data structures, master algorithmic thinking, and develop the problem-solving skills needed for coding interviews. At VertexClass, we believe complex programming concepts become easier when you can actually see what’s happening. Instead of relying only on slides or code explanations, this course combines custom-built animations, step-by-step Python implementations, practical examples, coding exercises, quizzes, and LeetCode challenges to help you build a deeper understanding of each concept.

What You’ll Learn:

• Algorithm Analysis and Big O: Understand time and space complexity, analyze algorithm efficiency, and compare different approaches using Big O notation.
• Core Data Structures: Explore arrays, Python lists, linked lists, stacks, queues, hash tables, dictionaries, sets, trees, heaps, and graphs. Learn how each structure works internally, when to use it, and how its operations affect performance.
• Searching and Sorting Algorithms: Understand common searching and sorting techniques, their implementations, and their time and space complexity.
• Recursion and Problem-Solving Patterns: Build confidence with recursion and important algorithmic techniques such as two pointers, sliding windows, and other common coding interview patterns.
• LeetCode and Coding Interviews: Apply your knowledge to practical LeetCode problems. Learn to identify patterns, develop solutions, optimize performance, and explain your reasoning clearly.
