Given a set of broadcast emitting stations s1 ,...,sn , a list of frequencies f1 ,...,fm , where m ≥ n, and the set of adjacent stations E = {(si ,sj )}. The goal is to assign a frequency to each station so that adjacent stations use different frequencies and the number of used frequencies is minimized. Formulate this problem as an integer linear programming problem.

Write a method that takes in an array of point2d objects, and then analyzes the dataset to find points that are close together. be sure to review the point2d api. in your method, if the distance between any pair of points is less than 10, display the distance and the (x, y)s of each point. for example, "the distance between (3,5) and (8,9) is 6.40312." the complete api for the point2d adt may be viewed at ~pf/sedgewick-wayne/algs4/documenta tion/point2d. html (links to an external site.)links to an external site.. try to write your program directly from the api - do not review the adt's source code.
