Lazy Running
Problem Description
In HDU, you have to run along the campus for 24 times, or you will fail in PE. According to the rule, you must keep your speed, and your running distance should not be less than meters. There are checkpoints in the campus, indexed as and . Every time you pass a checkpoint, you should swipe your card, then the distance between this checkpoint and the last checkpoint you passed will be added to your total distance. The system regards these checkpoints as a circle. When you are at checkpoint , you can just run to or ( is also next to ). You can run more distance between two adjacent checkpoints, but only the distance saved at the system will be counted.
Checkpoint is the nearest to the dormitory, Little Q always starts and ends running at this checkpoint. Please write a program to help Little Q find the shortest path whose total distance is not less than .
Input
The first line of the input contains an integer , denoting the number of test cases. In each test case, there are integers $K,d_{1,2},d_{2,3},d_{3,4},d_{4,1}(1\leq K\leq 10^{18},1\leq d\leq 30000)$, denoting the required distance and the distance between every two adjacent checkpoints.
Output
For each test case, print a single line containing an integer, denoting the minimum distance.
Sample Input
1
2000 600 650 535 380
Sample Output
2165
Hint
The best path is 2-1-4-3-2.
