<p>
The mismatch() function compares the elements in the range defined by
[start1,end1) to the elements in a range of the same size starting at start2.
</p>

<p>
The return value of <code>mismatch()</code> is either:
</p>
<ul>
<li class="level1"><div class="li"> The first location where the two ranges differ.</div>
</li>
<li class="level1"><div class="li"> If the ranges are equal, <code>end1</code> and the corresponding element in second range.</div>
</li>
</ul>

<p>

If the optional binary predicate <code>p</code> is given, then it is used to compare
elements from the two ranges.
</p>

<p>
The <code>mismatch()</code> algorithm runs in <a href="../../complexity.html" class="wikilink1" title="complexity">linear time</a>.
