Easy Accuracy: 38.42% Submissions: 1943 Points: 2

Given two array A[0….N-1] and B[0….M-1] of size N and M respectively, representing two numbers such that every element of arrays represent a digit. For example, A[] = { 1, 2, 3} and B[] = { 2, 1, 4 } represent 123 and 214 respectively. The task is to find the sum of both the numbers.

Input:

The first line of input contains an integer T denoting the number of test cases. Then T test cases follow.
Each testcase contains 4 lines:-
size of first array denoted by N
N elements of first array, separated by a space
size of second array denoted by M
M elements of second array, separated by a space

Output:
Print the sum of the numbers represented by the arrays.

Constraints:

1<=T<=100
2<=N<=9
2<=M<=9

Example:

Input:
3
2
1 2
2
2 1
4
9 5 4 9
3
2 1 4
3
1 2 3
3
2 1 4

Output:
33
9763
337

Explanation:
For testcase 1:
N=2, and A[]={1,2}
M=2, and B[]={2,1}
Number represented by first array is 12.
Number represented by second array is 21
Sum=12+21=33
