ALGOHAY
Algorithms, demystified — data-structure guides, complexity tools, and interview prep for developers.
From analyzing Big O growth and solving recurrences with the Master Theorem to working through amortized and recursion-tree analysis, estimating interview complexity, and comparing the classic algorithms, AlgoHay pairs free hands-on complexity tools with practical guides and a richly illustrated museum. Reason clearly, code faster.
Algorithm & Complexity Tools
Free tools for reasoning about algorithms — Big O complexity analyzer, Master Theorem solver, amortized analysis calculator, recursion tree calculator, interview complexity estimator, and an algorithm comparison table.
Big O Complexity Analyzer
Compare the common growth classes — O(1) through O(n!) — at any input size, rank their operation counts, and see which of two complexities dominates as n grows
Master Theorem Calculator
Solve divide-and-conquer recurrences T(n)=a·T(n/b)+Θ(n^d) — enter a, b, and d to get log_b(a), the case that applies, and the tight Θ bound with validation
Amortized Analysis Calculator
Use the aggregate method on a doubling dynamic array to see the total cost across n appends and why the amortized cost per operation stays O(1)
Recursion Tree Calculator
Expand T(n)=a·T(n/b)+n^d level by level — subproblem count, size, and work per level — then sum the total work and count the log_b(n) levels
Interview Complexity Estimator
Pick the techniques your solution uses and the input-size regime for a rules-based read on expected time and space complexity, plus a difficulty band
Algorithm Comparison Tool
Weigh up classic sorts, searches, and graph traversals across best/average/worst time, space, and stability — and rank them by operation count at any n
Museum of Algorithms
Wander an immersive museum of the ideas that shape the way we compute — classic algorithms and the data structures behind them alongside the pioneers who founded the field and the theory and foundations that make it rigorous, each in its own gallery, so you can get to know the stories behind every great idea: how each one came to be, what makes it matter, and the role it plays in shaping how we build software.

Fresh guides on sorting and searching, data structures, complexity and Big O, dynamic programming, and graph algorithms, plus practical tips for analyzing code, acing technical interviews, and writing faster, cleaner algorithms.
