Problem: There are nn water tanks in a row, ii-th of them contains aia_i liters of water. The tanks are numbered from 11 to nn from left to right.

You can perform the following operation: choose some subsegment [l,r][l, r] (1lrn1\le l \le r \le n), and redistribute water in tanks l,l+1,,rl, l+1, \dots, r evenly. In other words, replace each of al,al+1,,ara_l, a_{l+1}, \dots, a_r by al+al+1++arrl+1\frac{a_l + a_{l+1} + \dots + a_r}{r-l+1}. For example, if for volumes [1,3,6,7][1, 3, 6, 7] you choose l=2,r=3l = 2, r = 3, new volumes of water will be [1,4.5,4.5,7][1, 4.5, 4.5, 7]. You can perform this operation any number of times.

What is the lexicographically smallest sequence of volumes of water that you can achieve?

As a reminder:

A sequence aa is lexicographically smaller than a sequence bb of the same length if and only if the following holds: in the first (leftmost) position where aa and bb differ, the sequence aa has a smaller element than the corresponding element in bb.

Input Format: The first line contains an integer nn (1n1061 \le n \le 10^6) — the number of water tanks.

The second line contains nn integers a1,a2,,ana_1, a_2, \dots, a_n (1ai1061 \le a_i \le 10^6) — initial volumes of water in the water tanks, in liters.

Because of large input, reading input as doubles is not recommended.

Output Format: Print the lexicographically smallest sequence you can get. In the ii-th line print the final volume of water in the ii-th tank.

Your answer is considered correct if the absolute or relative error of each aia_i does not exceed 10910^{-9}.

Formally, let your answer be a1,a2,,ana_1, a_2, \dots, a_n, and the jury's answer be b1,b2,,bnb_1, b_2, \dots, b_n. Your answer is accepted if and only if aibimax(1,bi)109\frac{|a_i - b_i|}{\max{(1, |b_i|)}} \le 10^{-9} for each ii.

Note: In the first sample, you can get the sequence by applying the operation for subsegment [1,3][1, 3].

In the second sample, you can't get any lexicographically smaller sequence.
