Problem Statement

You are given $a permutation P=(P _ 1,P _ 2,\ldots,P _ N)$ of $(1,2,\ldots,N)$.
Find the following value for all i\ $(1\leq i\leq N)$:

  • $D _ i=\displaystyle\min_{j\neq i}\left\lparen\left\lvert P _ i-P _ j\right\rvert+\left\lvert i-j\right\rvert\right\rparen$.

What is a permutation?

A permutation of $(1,2,\ldots,N)$ is a sequence that is obtained by rearranging $(1,2,\ldots,N)$.
In other words, a sequence A of length N is a permutation of $(1,2,\ldots,N)$ if and only if each i\ $(1\leq i\leq N)$ occurs in A exactly once.

Input

The input is given from Standard Input in the following format:
N
$P _ 1 P _ 2 \ldots P _ N$

Output

Print D _ i\ $(1\leq i\leq N)$ in ascending order of i, separated by spaces.

Constraints

  • $2 \leq N \leq 2\times10^5$
  • $1 \leq P _ i \leq N$\ $(1\leq i\leq N)$
  • $i\neq j\implies P _ i\neq P _ j$
  • All values in the input are integers.

For example, for i=1,

  • if j=2, we have $\left\lvert P _ i-P _ j\right\rvert=1$ and $\left\lvert i-j\right\rvert=1$;
  • if j=3, we have $\left\lvert P _ i-P _ j\right\rvert=1$ and $\left\lvert i-j\right\rvert=2$;
  • if j=4, we have $\left\lvert P _ i-P _ j\right\rvert=2$ and $\left\lvert i-j\right\rvert=3$.

Thus, the value is minimum when j=2, where $\left\lvert P _ i-P _ j\right\rvert+\left\lvert i-j\right\rvert=2$, so D _ 1=2.
