问题描述

你将获得 $N$ 个由小写英文字母组成的字符串。设第 $i$ 个（$i = 1, 2, \dots, N$）字符串为 $S_i$。

对于两个字符串 $x$ 和 $y$，定义 $\mathrm{LCP}(x, y)$ 为满足以下所有条件的最大整数 $n$：

• 字符串 $x$ 和 $y$ 的长度均至少为 $n$。
• 对于所有在 $1$ 到 $n$ 之间（含）的整数 $i$，第 $i$ 个字符的 $x$ 值和 $y$ 值相等。

求出对所有 $i = 1, 2, \dots, N$ 的以下值：

• $\displaystyle \max_{i \neq j} \mathrm{LCP}(S_i, S_j)$

以上为通义千问 qwen-max 翻译，仅供参考。

Problem Statement

You are given $N$ strings consisting of lowercase English letters. Let $S_i$ be the $i$-th $(i = 1, 2, \dots, N)$ of them.

For two strings $x$ and $y$, $\mathrm{LCP}(x, y)$ is defined to be the maximum integer $n$ that satisfies all of the following conditions:

• The lengths of $x$ and $y$ are both at least $n$.
• For all integers $i$ between $1$ and $n$, inclusive, the $i$-th character of $x$ and that of $y$ are equal.

Find the following value for all $i = 1, 2, \dots, N$:

• $\displaystyle \max_{i \neq j} \mathrm{LCP}(S_i, S_j)$

Constraints

• $2 \leq N \leq 5 \times 10^5$
• $N$ is an integer.
• $S_i$ is a string of length at least $1$ consisting of lowercase English letters $(i = 1, 2, \dots, N)$.
• The sum of lengths of $S_i$ is at most $5 \times 10^5$.

Input

The input is given from Standard Input in the following format:

$N$

$S_1$

$S_2$

$\vdots$

$S_N$

Output

Print $N$ lines. The $i$-th $(i = 1, 2, \dots, N)$ line should contain $\displaystyle \max_{i \neq j} \mathrm{LCP}(S_i, S_j)$.
