#include <algorithm>
  iterator search_n( iterator start, iterator end, size_t num, const TYPE& val );
  iterator search_n( iterator start, iterator end, size_t num, const TYPE& val, BinPred p );

The search_n() function looks for num occurances of val in the range [start,end).

If num consecutive copies of val are found, search_n() returns an iterator to the beginning of that sequence. Otherwise it returns an iterator to end.

If the optional binary predicate p is given, then it is used to perform comparisons between elements.

This function runs in linear time.
