442 Design and Analysis of Algorithms
16.3 TIME-SPACE TRADE-OFF
As we have seen, an algorithm’s effi ciency can be expressed in terms of time or memory space requirement.
The space required will depend upon the number and size of the variables, arrays, and other complex data
structures used by the algorithm. The time required depends upon the number of elementary operations that
are required to be done.
In many cases, the space and time required by an algorithm are inversely related, that is, we may be
able to reduce the execution time by increasing the space available to the algorithm. Taking advantage of
this phenomenon is called time-space ...
