\defgroup gather gather
\ingroup mutating_algorithm
\c gather() takes a collection of elements defined by a pair of iterators and moves
the ones satisfying a predicate to them to a position (called the pivot) within
the sequence. The algorithm is stable. The result is a pair of iterators that
contains the items that satisfy the predicate.
Given an sequence containing:
<pre>
0 1 2 3 4 5 6 7 8 9
</pre>
a call to gather ( arr, arr + 10, arr + 4, IsEven ()) will result in:
<pre>
1 3 0 2 4 6 8 5 7 9
|---|-----|
first | second
pivot
</pre>
The problem is broken down into two basic steps, namely, moving the items before the pivot
and then moving the items from the pivot to the end. These "moves" are done with calls to
stable_partition.
\par Storage Requirements:
The algorithm uses stable_partition, which will attempt to allocate temporary memory,
but will work in-situ if there is none available.
\par Time Complexity:
If there is sufficient memory available, the run time is linear in <code>N</code>.
If there is not any memory available, then the run time is <code>O(N log N)</code>.
