In the Settlers of Catan, you can't place a settlement within two spaces of another settlement. In this advanced version of Catan, the rules are a little different. You can't place a settlement in a location that is within k spaces of all existing settlements (or on top of an existing settlement) (So a settlement that is within k spaces of some existing settlements but not every existing settlement is legal.) Your task is, given a board and a number k, determine the number of offlimit locations for a settlement. Input The first line contains an integer k, distance required from settlements The next line contains an integer r, the number of settlements. The next x lines contain the unique identifiers for those k settlements. The following line contains an integer n, the number of positions on the board The next n lines contain a unique identifier for that position, followed by a colon followed by a comma-separated list of adjacent positions Constraints You may assume the positions form an undirected, connected graph.
