Background

As everyone knows, a coconut is a coconut, but this seems to have nothing to do with the problem.

Problem Description

You are given a sequence aa of length nn. We guarantee that every number from 11 to nn appears in aa exactly once. For each 1in1\le i\le n, after changing the value ii in the sequence to 11, find how many different subarray gcd\gcd values the sequence has.

More precisely, let AxA^x be the sequence after changing the number with value xx to 11. Define the set $S_x=\{\gcd\limits_{i=l}^r(A^x_i)|1\le l\le r\le n\}$. Compute Si|S_i| for all ii.

Input Format

The first line contains a positive integer nn, the length of the permutation.

The next line contains nn positive integers, the sequence aa.

Output Format

Output one line with nn integers in total. The ii-th integer denotes the number of different subarray gcd\gcd values after changing the number with value ii to 11.

Hint

Sample Explanation 1

After changing 11 to 11, there are 33 different subarray gcd\gcd values: {1,2,3}\{1,2,3\}. They can correspond to subarrays [1,3][1,3], [3,3][3,3], and [1,1][1,1], respectively.

After changing 22 to 11, there are 22 different subarray gcd\gcd values: {1,3}\{1,3\}. They can correspond to subarrays [2,3][2,3] and [1,1][1,1], respectively.

After changing 33 to 11, there are 22 different subarray gcd\gcd values: {1,2}\{1,2\}. They can correspond to subarrays [1,2][1,2] and [3,3][3,3], respectively.

Constraints and Notes

This problem uses bundled testdata.

Subtask\text{Subtask} Score Constraints Special Property
11 1010 n20n\le 20 No special restrictions.
22 2020 n200n\le 200
33 3030 n2000n\le 2000
44 2020 No special restrictions. AA.
55 No special restrictions.

AA: For all 1in1\le i\le n, we have ai=ia_i=i.

For all testdata, 2n5×1052\le n\le 5\times 10^5. We guarantee that every number from 11 to nn appears in aa exactly once.
