You are given a positive integer n, that is initially placed on a board. Every day, for 109 days, you perform the following procedure:

\n\n\n\n

Return the number of distinct integers present on the board after 109 days have elapsed.

Note:

Example 1:

\n\n
\nInput: n = 5\nOutput: 4\nExplanation: Initially, 5 is present on the board. \nThe next day, 2 and 4 will be added since 5 % 2 == 1 and 5 % 4 == 1. \nAfter that day, 3 will be added to the board because 4 % 3 == 1. \nAt the end of a billion days, the distinct numbers on the board will be 2, 3, 4, and 5. \n
\n\n

Example 2:

\n\n
\nInput: n = 3\nOutput: 2\nExplanation: \nSince 3 % 2 == 1, 2 will be added to the board. \nAfter a billion days, the only two distinct numbers on the board are 2 and 3. \n
