Permutations differ from combinations, which are selections of some members of a set regardless of … By listing and labeling all of the permutations in order, We get the following sequence (ie, for n = 3): "123" "132" "213" "231" "312" "321" Given n and k, return the k th permutation sequence. A derangement of S is as any permutation of S such that no two elements in S and its permutation occur at same position. Since k + 1 is such an index, l is well defined and satisfies k < l.

If such an arrangement is not possible, it must rearrange it as the lowest possible order (i.e., sorted in ascending order). Les fonctions pre et post génèrent des séquences ordonnées de la forme: pre (T) = [A, B, pre ( C), pre ( D)] poste (T) = [ poste ( C), B, poste ( D), A] où la fonction appliquée à un vecteur est définie comme étant la concaténation des séquences résultant de l'application de la fonction à chaque élément.
