One day, the Scratch Cat decided to use his hacker skills to shut down all websites in Yuboland. There are $N$ websites available for him to hack. However, the Scratch Cat isn't intelligent enough to decide whether a website is hosted by Yuboland.

Therefore, he came up with a rule to determine that. The Scratch Cat believes that a website is hosted by Yuboland if

1. yubo (all lowercase) is a substring of the website's URL,
2. The website is directly before or after a website that satisfies the first rule.

Please determine the websites that the Scratch Cat will hack in alphabetical order.

Constraints

$1\le N\le {10}^4$

$1\le |s_i|\le 100$

Input Specification

The first line will contain an integer $N$, the number of websites available for the Scratch Cat to hack.

The next $N$ lines will each contain a string $s_i$, the URL for the $i^{\text{th}}$ website.

Output Specification

Output the URLs of the websites that the Scratch Cat will hack in alphabetical order. Do not output duplicate URLs.

Sample Input

5
dmoj.ca
scratch.mit.edu
yubosucks.scratch
scratch.mit.edu
canada.ca

Sample Output

scratch.mit.edu
yubosucks.scratch

Explanation

The second URL, scratch.mit.edu, is directly before a URL containing yubo as a substring. The third URL directly contains yubo. The fourth URL is identical to the second and is directly after a URL containing yubo. The sorted list of URLs is then $\{$scratch.mit.edu, yubosucks.scratch$\}$. Notice two scratch.mit.edu URLs that satisfy the conditions, but only one is output because they are the same website.
