Function template partition_copy

boost::algorithm::partition_copy — Copies the elements that satisfy the predicate p from the range [first, last) to the range beginning at d_first_true, and copies the elements that do not satisfy p to the range beginning at d_first_false.

Synopsis

// In header: <boost/algorithm/cxx11/partition_copy.hpp>


template<typename InputIterator, typename OutputIterator1, 
         typename OutputIterator2, typename UnaryPredicate> 
  BOOST_CXX14_CONSTEXPR std::pair< OutputIterator1, OutputIterator2 > 
  partition_copy(InputIterator first, InputIterator last, 
                 OutputIterator1 out_true, OutputIterator2 out_false, 
                 UnaryPredicate p);

Description

	Note
	This function is part of the C++2011 standard library.

Parameters:

`first`	The start of the input sequence
`last`	One past the end of the input sequence
`out_false`	An output iterator to write the elements that do not satisfy the predicate into
`out_true`	An output iterator to write the elements that satisfy the predicate into
`p`	A predicate for dividing the elements of the input sequence.
