<p>In computer science, a data structure is a way of storing
data in a computer so that it can be used efficiently. Often,
a carefully chosen data structure will allow a more efficient
algorithm to be used. The choice of the data structure often
begins from the choice of an abstract data structure. A
well-designed data structure allows a variety of critical
operations to be performed on using as little resources, both
execution time and memory space, as possible.</p>
