To translate a Chinese sentence into cyber language, you need to find the first letter of each Chinese character, and write it in upper-case.

You will be given several Chinese sentences, please translate them into the cyber language described above.

The first line contains a single integer $T$ ($1 \leq T \leq 10$), the number of test cases. For each test case:

The only line contains several Chinese characters written in lower-case, separated by exactly one space. It is guaranteed that the length of each line is at least $1$ and at most $50$.
