Problem F - The Bridges of Kšlsberg
King Beer has a very hard region to rule,
consisting of lots of cities with very sectarian operating system beliefs and
high levels of trade. These cities are placed along a river, the Kšlsberg,
along its Northern and Southern banks. The cities are economically separated
from each other, since the river is wide and dangerous.
A section of the Kšlsberg showing some invalid
bridges
The economical value of a bridge is the
sum of the trade values the two cities it connects. The King wants to maximize
the sum of all possible bridge values while minimizing the number of bridges to
build.
Given two sets of cities, return the
maximum possible sum of all bridge values and the smallest number of valid
bridges necessary to achieve it.
The first line is an integer with the number of samples. For each sample, the next line has a non-negative integer, not greater than 1,000, indicating the number of cities on the Northern riverbank. Then, on each line, comes the city information with the form
cityname
ostype tradevalue
where, separated by empty spaces, there are two strings, cityname and ostype, with no more than 10 characters each, and tradevalue which is a non-negative integer not greater than 106. The sequence of lines represents the cities from left to right along the riverbank. Next, there is the same kind of information to describe the Southern riverbank.
For each sample, a line consisting of the maximum possible sum of all bridge values, one empty space, the number of bridges.
