next permutation
nextPermutation :: (PrimMonad m, Ord e, MVector v e) => v (PrimState m) e -> m Bool #
Compute the (lexicographically) next permutation of the given vector in-place.
Returns False when the input is the last permutation; in this case the vector
will not get updated, as opposed to the behavior of the C++ function
std::next_permutation.
nextPermutationBy :: (PrimMonad m, MVector v e) => (e -> e -> Ordering) -> v (PrimState m) e -> m Bool #
Compute the (lexicographically) next permutation of the given vector in-place,
using the provided comparison function.
Returns False when the input is the last permutation; in this case the vector
will not get updated, as opposed to the behavior of the C++ function
std::next_permutation.
prevPermutation :: (PrimMonad m, Ord e, MVector v e) => v (PrimState m) e -> m Bool #
Compute the (lexicographically) previous permutation of the given vector in-place.
Returns False when the input is the last permutation; in this case the vector
will not get updated, as opposed to the behavior of the C++ function
std::next_permutation.
prevPermutationBy :: (PrimMonad m, MVector v e) => (e -> e -> Ordering) -> v (PrimState m) e -> m Bool #
Compute the (lexicographically) previous permutation of the given vector in-place,
using the provided comparison function.
Returns False when the input is the last permutation; in this case the vector
will not get updated, as opposed to the behavior of the C++ function
std::next_permutation.
