|
|
<ul>
|
|
|
<li>Algorithms: processes that operate on data</li>
|
|
|
<li>Programs: implementations of algorithms</li>
|
|
|
<li>Data in programs: stored in data structures
|
|
|
<ul>
|
|
|
<li>simple D.S.: variables</li>
|
|
|
<li>most algorithms required compound D.S.s: e.g. arrays, lists, …</li>
|
|
|
<li>most non-trivial applications require non-trivial D.S.s</li>
|
|
|
</ul>
|
|
|
</li>
|
|
|
<li>Data Type: collection of values + operations on these values</li>
|
|
|
<li>Multiple data types:
|
|
|
<ul>
|
|
|
<li>Cleaner/simpler slg. design</li>
|
|
|
<li>better code</li>
|
|
|
</ul>
|
|
|
</li>
|
|
|
<li>Abstract Data Type: defined by values + operations without reference to how things are implemented</li>
|
|
|
<li>ADTs provide an abstract view of data:
|
|
|
<ul>
|
|
|
<li>let us reason about algorithms at a high level, ignoring implementation details</li>
|
|
|
</ul>
|
|
|
</li>
|
|
|
<li>Good ADT choices reduce program complexity & increase likelihood of success ( which is good).</li>
|
|
|
<li>a[i] vs. a(i)</li>
