Syntax:
#include <algorithm> forward_iterator search_n( forward_iterator start, forward_iterator end, SIZE num, const TYPE& val ); forward_iterator search_n( forward_iterator start, forward_iterator end, SIZE 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.
