You are given an integer n.

\n\n

Each number from 1 to n is grouped according to the sum of its digits.

\n\n

Return the number of groups that have the largest size.

Example 1:

\n\n
\nInput: n = 13\nOutput: 4\nExplanation: There are 9 groups in total, they are grouped according sum of its digits of numbers from 1 to 13:\n[1,10], [2,11], [3,12], [4,13], [5], [6], [7], [8], [9].\nThere are 4 groups with largest size.\n
\n\n

Example 2:

\n\n
\nInput: n = 2\nOutput: 2\nExplanation: There are 2 groups [1], [2] of size 1.\n
