16.1 INTRODUCTION
We have already seen that the effi ciency considerations for algorithms are inherently connected with its
design and implementation. Every algorithm when implemented, must use some of the system resources
to complete its task. The resources most relevant to effi ciency are the usage of the central processor unit
(CPU) time and internal memory (RAM). In the past, due to the relatively high cost of computer resources,
it was desirable to design algorithms that were economical in the use of CPU time and memory. Algorithm
effi ciency has become inevitable due to the following reasons:
1. There are many applications where strict time limits on execution time and/or space requirements are to
be observed.
2. ...
