In the first approximation, the capacity of the tank should be at least as large as to cover the maximum distance between the drums
In the last one too. And if this condition is fulfilled, it is possible to run the route in any direction. (Only you may have to start from different barrels).
No. That's not good enough! I can give you an example....
You need a minimum distance too !
No. That's not good enough! I can give you an example....
You also need a minimum distance !
... And since the maximum section without barrels can be made as close as possible to the length of the circle, the tank must hold exactly 100 litres, no more, no less, to guarantee passage through it.
For a guaranteed "in all cases", yes.
It's interesting to check Manov's claim that there could be an arrangement where passage is only possible in one direction. (With a limitation on tank size < 100)
Come on.
Give us an example first, then we'll see.Tank capacity =30 litres. You can do 31, 32.
Tank capacity =30 litres. You could do 31, 32.
Yep, convinced. Capacity must be at least Max+Min.
However, this example is symmetrical. If the condition (Max+Min) is met, passage is possible in both directions.
What about the "one-pass" example?
Tank capacity =30 litres. Can also be 31, 32
I haven't considered the other options that have now come out, but I'll post my decision nonetheless:
A: It is possible, in any direction.
.............................
The new MegaFunction will immediately start with a big jump at zero (30L) and will obviously be no lower than zero everywhere.
Please note that the driving direction hasn't changed, and it doesn't have to. It is sufficient to choose the starting point of the graph correctly and drive from it.
Yep, beautiful.
Obviously a cyclist can start in both directions with a similar result (finding the right start). Although the starting point might be different.
The question arises: Is it possible for the minimum to be different in magnitude, moving in different directions?
The answer would shed light on the possibility that a "nipple" exists, in the form of a tank size constraint (Min1 < V tank < Min2).
