String aa is a substring of string bb if it is possible to choose several consecutive letters in bb in such a way that they form aa. For example, string "for" is contained as a substring in strings "codeforces", "for" and "therefore", but is not contained as a substring in strings...

For example, string "for" is contained as a substring in strings "codeforces", "for" and "therefore", but is not contained as a substring in strings "four", "fofo" and "rof". Input The first line contains an integer nn (1≤n≤1001≤n≤100) — the number of strings. The next ...

Now I wanted to know that can this type of case happen during a submission in Codeforces or It can never happen. Sorry for silly question. Thanks in advance.
The robot is off at the moment. Imp knows that it has a sequence of stringstiin its memory, and he can arbitrary change their order. When the robot is started, it generates the stringtas a concatenation of these strings in the given order. The noise of the resulting string equals the ...
