Every morning Fujian wakes up and walks through the barn from his farm. The farm is a set of fields 1=n=250 mbidirectional pathways connected 1=m=million, each with an associated length. The house in Fujian is in 1 field, the site of the barn.
isjoined by multiple redundant path fields without a pair, can travel betweenany fields in a double farm, in an appropriate sequence ofpathways. When traveling from one pasture to another, Fujian always chooses the minimum total length sequence of the aroute pathway. Farmer John Bull, not as good as ever, decided to interfere with his morning routine.
They planned to build a haystack on the farm with a m channel to make it long. The cattle want to block the toselect route so that they can maximize their growth in Fujian'sdistance from home to barn. Please help the cows determineby how much they can extend the route of Fujian.

Waking up every morning, FJ walks through the farm from his barn. The farm is a collection of n-domains (1 n 250) connected by mbidirectional pathways (1 m 25000), each of which is associated with a length. The FJ house is in 1 field, and the barn is on site, there are no multiple redundant paths to connect to the domain, it is made up of a proper order ofpathways along the field of walking along the farm will travel.
When moving from one field to another, Fujian always chooses a route consisting of a sequence of paths with the lowest total length. Farmer John's cows, always not getting better, decided to interfere with his morning routine. They plan to build a bunch of hay bales in a meter of the way completely on the farm, doubling its length.
The cow wants to choose a path block so that they can maximize the FJ from the house'sdistance to the barn. Please help the cows determineby how they can extend the FJ's route more.
