Backtracking is how computers solve mazes, puzzles, and impossible-looking problems: try a path, and if it fails, undo and try another. This book turns that idea into a visual, story-driven guide through classic problems like N-Queens, Sudoku, and permutations. You'll learn how decision trees work, how and when to prune bad paths early, a "e;Spot the Concept"e; section, and practice problems with full solutions plus an interview-prep angle.
