Textbook errors in binary searching

Richard E. Pattis
1988 Proceedings of the nineteenth SIGCSE technical symposium on Computer science education - SIGCSE '88  
This paper discusses the specification and implementation of binary searching. It begins by presenting a "staudard" set of declarations, a specification, and a binary searching procedure written in Pascal. This procedure does not meet the specification: it contains five errors that also occur in many CS-1 and CS-2 textbooks. We will locate and study these errors, and show alternative procedures that correct them in a simple and understandable way.
