You all know Emrul bhai, right? He is a genius guy. He knows how to add two integer numbers and so do you.

```
56
+25
----
81
```

He has a crush and her facebook name is “Sweety girl Jorina”. One day Emrul bhai's friend Rafat bhai challenged him if his juinors from first year can make a program that adds two very large numbers, then they will make a meeting for him with his crush.

Now Emrul bhai came running to you sweating and asked "Can you please do it for me so that I can meet my sweety girl?”.

You will be given a test case $T$ ($1 \le T \le 100$). In each case, you will be given two numbers $A$ and $B$ ($0 \le \texttt{Digits in A and B} \le 10^5$).

For each case, you have to print the case number and the summation of the given numbers.

Input | Output |

Number A and B can be very large.

You can't store in int or long long int data type if digits number in a number is greater than 18. You have to store it in a string.

It is guaranteed that summation of A and B won’t contain leading zero’s.
