Progressive climate change has forced the Byteburg authorities to build a huge lightning conductor that would protect all the buildings within the city. These buildings form a row along a single street, and are numbered from $1$ to $n$.
The heights of the buildings and the lightning conductor are non-negative integers. Byteburg's limited funds allow construction of only a single lightning conductor. Moreover, as you would expect, the higher it will be, the more expensive.
The lightning conductor of height $p$ located on the roof of the building $i$ (of height $h_i$) protects the building $j$ (of height $h_j$) if the following inequality holds:
$$h_j \le h_i + p - \sqrt{|i - j|},$$
where $|i-j|$ denotes the absolute value of the difference between $i$ and $j$.
Byteasar, the mayor of Byteburg, asks your help. Write a program that, for every building $i$, determines the minimum height of a lightning conductor that would protect all the buildings if it were put on top of the building $i$.
Input
In the first line of the standard input there is a single integer $n$ ($1 \le n \le 500,000$) that denotes the number of buildings in Byteburg. Each of the following $n$ lines holds a single integer $h_i$ ($0 \le h_i \le 1,000,000$) that denotes the height of the $i$-th building.
Output
Your program should print out exactly $n$ lines to the standard output. The $i$-th line should give a non-negative integer pi denoting the minimum height of the lightning conductor on the $i$-th building.
