The phrase "Na Za La???" originates from a rhetorical question in the Northeastern Chinese dialect. After spreading through the internet, it has evolved into three core meanings:

• Questioning function: When disagreeing with others' opinions, people use rhetorical questions to ask for further explanation. This is also jokingly called a "don't care" attitude towards life by netizens.

• Social buffer: used as a transitional phrase in conversations where there is nothing else to say;

• Attitude expression: Shows a nonchalant attitude towards the outcome of things, such as "You failed the test? — Na Za La?", conveying an optimistic attitude towards life that is not consumed by internal friction and is not influenced by others.

Timothy had a microeconomics exam in two days, and he felt completely clueless. But his roommate insisted he play Valorant. Timothy, already anxious, planned to spend about 30 minutes reasoning with his roommate, only for his roommate to start with "Na Za La" ("What's wrong with that?") at zero frame.

Timothy was speechless, at a loss for words. Then, an idea struck him: consider his roommate's behavior a human-machine interaction, demonstrating that even machines can do this. He then developed a "So automaton" that, regardless of the input, would output "Na Za La?"

Input

The first line contains a number $t$($1\leq t\leq 10^5$).

The next $t$ lines each contain a sentence Timothy says to his roommate.

Output

Finally, a string $\tt{Na\ Za\ La?}$ is output. Please use the Western question mark punctuation.
