Description

A sentence is defined as $A\underline{\texttt{ : }}B\underline{\texttt{ is }}C\underline{\texttt{.}}$, where $A$, $B$, and $C$ are strings representing the speaker's name, the subject of the sentence, and the predicative, respectively.

A sentence is considered nonsense if and only if the speaker is calling themselves weak—that is, $A$ is the same as $B$ and $C=\underline{\texttt{weak}}$.

Now, you need to determine whether the given sentence is nonsense. If it is, output Plang.; otherwise, output Not plang..

Input Format

A single line containing a string in the form of $A\underline{\texttt{ : }}B\underline{\texttt{ is }}C\underline{\texttt{.}}$. It is guaranteed that $A$, $B$, and $C$ consist solely of lowercase English letters.

Output Format

A single line. If the given sentence is nonsense, output Plang.; otherwise, output Not plang..

zxx : zxx is weak.

Plang.

zxx : ou is strong.

Not plang.

zxx : zxx is cute.

Not plang.

Hint

Explanation for Sample #1

In the first sample, $A=\text{zxx}$, $B=\text{zxx}$, and $C=\text{weak}$. Here, $\text{zxx}$ is calling themselves weak, which qualifies as nonsense. Therefore, the output should be Plang..

Data Range

• Special Property A: $C=\underline{\texttt{weak}}$.

For all test cases: It is guaranteed that $A$, $B$, and $C$ are strings consisting solely of lowercase English letters, with lengths between $1$ and $10$ (inclusive).
