How do you calculate lexicographic order?

One simple solution is

to initialize rank as 1

, generate all permutations in lexicographic order. After generating a permutation, check if the generated permutation is same as given string, if same, then return rank, if not, then increment the rank by 1.

What is lexicographic order of alphabet?

lexicographical order is

alphabetical order

. The other type is numerical ordering. Consider the following values, 1, 10, 2. Those values are in lexicographical order. 10 comes after 2 in numerical order, but 10 comes before 2 in “alphabetical” order.

What is lexicographically smallest array?

An array/list P is lexicographically smaller than its permutation Q if and only if, for the earliest index at which P and Q differ, P’s element at that index is smaller than Q’s element at that index. Example, P = [1, 12, 4, 7, 8] is lexicographically smaller than Q = [1, 12, 8, 4, 7].

How do you create lexicographic permutations?

2. Take the previously printed permutation and find the rightmost character in it, which is smaller than its next character. …
3. Now find the ceiling of the ‘first character’. …
4. Swap the two characters found in above 2 steps.
