Algorithms and Big-O Notation for Beginners

Writing code that works is only the first step—understanding how efficiently your solutions scale is essential for writing robust software. This text-based course guides you through core algorithmic thinking, breaking down time complexity, growth functions, and optimization patterns into clear, accessible concepts. What you'll learn: - Understand foundational algorithm terminology, computational thinking, and execution flow - Master Big-O notation to evaluate worst-case, best-case, and average-case performance - Analyze growth rates of logarithmic, linear, polynomial, and exponential functions - Compare naive recursion against optimized iterative approaches using Fibonacci sequences - Apply basic dynamic programming and memoization concepts to eliminate redundant operations - Evaluate time and space trade-offs to select efficient data structures and algorithms The course begins with foundational definitions and complexity metrics before walking you through comparative case studies and code analysis. It is designed specifically for beginners and self-taught developers seeking a clear conceptual introduction to algorithms with no prior theoretical background required.
