## Description

"I have a pen. I have an apple. Uh! Applepen."

"I have a pen. I have pineapple. Uh! Pineapplepen."

The above lyrics are taken from PPAP, a single by Pikotaro. It was released as a music video on YouTube on 25 August 2016, and has since become a viral video. As of October 2017, the official video has been viewed over 126 million times. Let's view this song from a mathematical perspective. In the lyrics there actually hides a function $\text{PPAP}(a, b)$, which takes two lowercased string $a$ and $b$ as the input and works as follows:

• First, calculate $s_1 = b + a$ ($+$ here means string concatenation).
• Then, capitalize the first character of $s_1$ to get $s_2$.
• Make $s_2$ as its output, and the function is done.

For example, we have PPAP("pen", "apple") = "Applepen", and PPAP("pen", "pineapple") = "Pineapplepen".

Given two lowercased strings $a$ and $b$, your task is to calculate $\text{PPAP}(a, b)$.

## Input

The first line of the input contains an integer $T$ (about 100), indicating the number of test cases. For each test case:

The first and only line contains two strings $a$ and $b$ ($1 \le |a|, |b| \le 30$) separated by one space. It's guaranteed that both $a$ and $b$ consist of only lowercase English letters.

## Output

For each test case output one line containing one string, indicating $\text{PPAP}(a, b)$.
