Reverse Number
All of you know better how to reverse a given number! Reversed number is a number written by reversing the order of digits. The first digit becomes last and vice versa.
For example, if the no is 1234 , the reverse of it will be 4321. Take care of the leading zeros (e.g. 5200 gives 25). It means reversed number never has any trailing zeros.
You have to find the sum of reverse of two given number and print the reverse of it.
Input First line of the input contains t, denotes number of testcases.
Following next t lines contains two numbers, denoting a,b.
0<= a,b <=1000000000 (10^9)
Output For each input(a,b), print exactly one line containing only one integer - the reversed sum of two reversed numbers. Omit any leading zeros in the output.
Sample input:
3
27 1
88 12
21 5
Sample output:
37
901
71
