to pick up the top or bottom card from either pile,and the score
of the card will be added to his total score.Alice and Bob are both
clever enough,and will pick up cards to get as many scores as possible.
Do you know how many scores can Alice get if he picks up first?
Input
The first line contains an integer T (T≤100),indicating the number of cases.
Each case contains 3 lines.The first line is the N (N≤20).The second line contains N integer ai (1≤ai≤10000).The third line contains N integer bi (1≤bi≤10000).
Output
For each case,output an integer,indicating the most score Alice can get.
