Function template prev

Function template prev_permutation

boost::compute::prev_permutation — Permutation generating algorithm.

Synopsis

// In header: <boost/compute/algorithm/prev_permutation.hpp>


template<typename InputIterator> 
  bool prev_permutation(InputIterator first, InputIterator last, 
                        command_queue & queue = system::default_queue());

Description

Transforms the range [first, last) into the previous permutation from the set of all permutations arranged in lexicographic order Space complexity: (1)

Parameters:

`first`	Iterator pointing to start of range
`last`	Iterator pointing to end of range
`queue`	Queue on which to execute

Returns:

Boolean value signifying if the first permutation was crossed and the range was reset
