factoradic造句

• Similarly if the second factoradic digit is " 1 ", the second is selected and then removed.
• The final factoradic digit is always " 0 ", and since the list now contains only one element it is selected as the last permutation digit.
• If the second factoradic digit is " 0 " then the first element of the list is selected for the second permutation digit and is then removed from the list.
• The leftmost factoradic digit 0, 1, or 2 is chosen as the first permutation digit from the ordered list ( 0, 1, 2 ) and is removed from the list.
• By necessity, therefore, the factoradic expansion of the reciprocal of a prime has a length of exactly that prime ( less one if the 1 / 1 ! place is omitted ).
• There is a natural mapping between the integers 0, . . ., " n " !  " 1 ( or equivalently the numbers with " n " digits in factorial representation ) and permutations of " n " elements in lexicographical order, when the integers are expressed in factoradic form.
