Let's introduce you to our very own Mishal Sir. After completing his Ph.D. from the University of Mars, he came back to the Earth and joined RIM (Rajan Institute of Mathematics).
Mishal sir had a very special sunglasses which he got as a special gift from one of his well-wishers at the University of Mars, but he never revealed who was that well-wisher (If you ever meet him in future, you may ask him about it and in case you find it out, do tell us about it).
The sunglasses is so special that if you wear it you won't see any space. You will just see characters and numbers only.
Palash The Tambourine Man was then a student of RIM. One day Palash The Tambourine Man forgot his glasses at home. It was Mishal sir's class and he, as usual, brought his sunglasses with him. Palash The Tambourine Man somehow snatched the sunglasses from Mishal sir and wore it.
Mishal sir gave him a line and asked him to write it. As Palash The Tambourine Man cannot see any space he just wrote down all the characters sequentially he found in that line.
Palash The Tambourine Man has a phobia called Hoofdaphobia. Hoofdaphobia is the fear of capital letters. So he never writes uppercase letters, he always converts them to lowercase letters.
Now write a program that will take a line from Mishal sir as input and print a line that Palash The Tambourine Man would write down.
Input
The first line of the input will contain a single integer T, the number of test cases.
For each test case, you will be given an integer n denoting the number of words
The next line will contain n words. No input file will have more than 100000 characters (including spaces). The words will contain only alphabets and numeric digits (0-9).
Output
For each test case, print a single line that "Palash The Tambourine Man" wrote down.
