Once upon an algorithm: how stories explain computing
In Once Upon an Algorithm, Erwig explains computation as something that takes place beyond electronic computers, and computer science as the study of systematic problem solving.
Erwig also discusses representations and different ways to organize data; "intractable" problems; language, syntax, and ambiguity; control structures, loops, and the halting problem; different forms of recursion; and rules for finding errors in algorithms. This book explains computation accessibly and shows its relevance to daily life.
