Designed to provide a comprehensive introduction to data structures and algorithms, including their design, analysis, and implementation, the text will maintain the same general structure as Data Structures. screenshot; Each letter of the alphabet has a position, starting at position 0. The code is fairly simple, a user enters an encryption key (which basically tells the program how to scramble the text, using an algorithm), then the text to be encrypted.
