Given two sorted arrays A and B. The task is to complete the function max_path_sum that takes 4 argument, the first two arguments represent the 2 arrays A and B and the last two arguments l1, l2 denote the size of array A and B respectively. The function returns the sum of the maximum sum path to reach from beginning of any array to end of any of the two arrays .
Note: You can switch from one array to another array only at common elements.
The first line of input contains an integer T denoting the no of test cases . Then T cases follow.
Each test case contains 3 lines. The first line contains two space separated integers l1 and l2 denoting the length of the two sorted array A and B. In the second line is the space separated values of array A and in the third line are space separated values of array B.
For each test case the output is the max sum obtained in such fashion .
1 <= T <= 100
1 <= N, M <= 103
1 <= A, B <= 104
2 3 7 10 12
1 5 7 8
1 2 4
1 2 7
Testcase 1: For first test case the path will be 1+5+7+10+12 = 35.
Testcase 2: For second test case the path will be 1+2 +7=10.
Note:The Input/Ouput format and Example given are used for system's internal purpose, and should be used by a user for Expected Output only. As it is a function problem, hence a user should not read any input from stdin/console. The task is to complete the function specified, and not to write the full code.
