[Updated] Time Complexity Deep Dive #1: Best & Worst Case Analysis Explained (2025 version)

#TimeComplexity #AlgorithmAnalysis #computerscience *Summary* This video introduces the fundamentals of time complexity analysis. We define key concepts like time complexity, algorithms, and the RAM model, and demonstrate how to analyze an algorithm’s efficiency. In the next video, we apply these concepts step by step to analyze insertion sort, breaking down every operation in detail.
