The first chapter mainly discusses some concepts, what is the algorithm, why the algorithm is worth studying.
Deep impression is the last sentence of the chapter, whether it has a solid foundation of algorithmic knowledge and technology is a distinguishing feature between a truly skilled programmer and a beginner. With modern computing, if you don't know much about algorithms, you can do a few things, but if you have a good algorithmic background, you can do much more.
Having a solid base of algorithmic knowledge and technique are one characteristic that separates the truly skilled programm ERs from the novices. With modern computing technology, you can accomplish some tasks without knowing much on algorithms, but with a good BAC Kground in algorithms, you can do much, much more .
