According to the shortest straight line distance, turning is not recommended.

When using one-way approach, there is no multi-direction approach. So arrange 100 cars in the square of 10* 10, and get into the cars from all directions.

When 36 cars are simply arranged, it is

1 2 3 3 2 1

2 1 2 2 1 2

3 2 1 1 2 3

3 2 1 1 2 3

2 1 2 2 1 2

1 2 3 3 2 1

along with

1 1

1 1

Center, the number is the number of vehicles passing by, and the minimum area is calculated at this time.

When there are 100 vehicles, the same calculation can be made.

-I thought of this method temporarily. The disadvantage is that L~2d is not considered, and it is best to arrange around 8 vehicles.

1 1 1 1

1 1 1 1

Rearrange in units of 2*4 vehicles.
