Wow! Such Conquering!Time Limit: 15000/8000 MS (Java/Others) Memory Limit: 32768/32768 K (Java/Others)Total Submission(s): 3107 Accepted Submission(s): 964 Problem Description There are n Doge Planets in the Doge Space. The conqueror of Doge Space is Super Doge, who is going to inspect his Doge Army on all Doge Planets. The inspection starts from Doge Planet 1 where DOS (Doge Olympic Statue) was built. It takes Super Doge exactly T_{xy} time to travel from Doge Planet x to Doge Planet y. With the ambition of conquering other spaces, he would like to visit all Doge Planets as soon as possible. More specifically, he would like to visit the Doge Planet x at the time no later than Deadline_{x}. He also wants the sum of all arrival time of each Doge Planet to be as small as possible. You can assume it takes so little time to inspect his Doge Army that we can ignore it. Input There are multiple test cases. Please process till EOF. Each test case contains several lines. The first line of each test case contains one integer: n, as mentioned above, the number of Doge Planets. Then follow n lines, each contains n integers, where the yth integer in the xth line is T_{xy} . Then follows a single line containing n  1 integers: Deadline_{2} to Deadline_{n}. All numbers are guaranteed to be nonnegative integers smaller than or equal to one million. n is guaranteed to be no less than 3 and no more than 30. Output If some Deadlines can not be fulfilled, please output “1” (which means the Super Doge will say “WOW! So Slow! Such delay! Much Anger! . . . ” , but you do not need to output it), else output the minimum sum of all arrival time to each Doge Planet. Sample Input
Sample Output
Hint Explanation: In case #1: The Super Doge travels to Doge Planet 2 at the time of 8 and to Doge Planet 3 at the time of 12, then to Doge Planet 4 at the time of 16. The minimum sum of all arrival time is 36. Source
