Notes: https://github.com/team-codebug/babua... 📘 Time & Space Complexity – The Right Way to Think (Not Memorize) Most interview candidates freeze when asked: “What’s the time and space complexity?” Not because they’re bad coders — but because they were never taught how to reason about performance. In this video, we fix that. This is Part 1 of the Babua Time & Space Complexity Course, where you’ll learn how interviewers actually expect you to think — logically, clearly, and at scale — without heavy math or rote memorization. 🚀 What you’ll learn in this video: Why interviewers really ask about time & space complexity How performance affects real production systems Why bad algorithms fail silently at scale Bubble Sort vs Merge Sort vs Java Built-in Sort (with real benchmarks) Why algorithm choice matters more than programming language Time vs Space trade-offs (and when to choose which) How to compare algorithms using growth, not stopwatch timing Best, worst, and average case — and why interviews care about worst case How to analyze algorithms step-by-step using instruction counts Full breakdown of Insertion Sort worst-case analysis How nested loops lead to O(n²) growth (with intuition) Why we generalize and move from exact counts to Big-O Proof of sum of n natural numbers (used in complexity analysis) 🎯 Who is this for? Beginners confused by time & space complexity Intermediate devs who can code but can’t explain performance Interview candidates preparing for product-based companies Anyone who wants to think like a system designer, not just a coder 💡 Key idea: Complexity is not about formulas. It’s about understanding how your code behaves as input grows. This video builds the foundation you need to analyze any algorithm confidently — in interviews and in real systems. 📌 Comment “Start” to begin the course 📌 Comment “Done” once you finish Part 1 Next videos will build on this and make complexity feel obvious, not scary.
