Algorithms, A Programmer’s Guide

Learn essential techniques for efficient code execution.

Decoding Algorithm Efficiency

Learn algorithm efficiency optimization: CPU cache lines, memory locality, branch prediction, and algorithmic trade-offs.

A comprehensive introduction to algorithmic thinking, problem decomposition, asymptotic efficiency, and interview strategies.

Master Breadth-First Search (BFS): level-by-level queue traversal, shortest path in unweighted graphs, and connected component discovery.

Master Binary Search: logarithmic search mechanics, monotonic boundaries, edge cases, and lower/upper bound determinations.

Master Depth-First Search (DFS): recursive call stack exploration, cycle detection, connected components, and pathfinding.

Understand Linear Search: sequential scanning, best/worst-case analysis, sentinel linear search, and when linear beats binary search.

Master the Bellman-Ford algorithm: shortest paths with negative edge weights, edge relaxation, and negative cycle detection in O(V*E).

Master Dijkstra's Shortest Path Algorithm: greedy distance relaxation using priority queues on weighted graphs with non-negative edges.

Master the Floyd-Warshall algorithm: all-pairs shortest paths on dense graphs using dynamic programming in O(V^3) time.

Master Bubble Sort: adjacent element comparisons, swap optimizations, early termination flags, and stability analysis.
