Do more with Bing Maps. map(F, List) is a function which takes a function F and a list L as arguments and returns the new list which is obtained by applying F to each of the elements in L. The process of abstracting out the common features of a number of different programs is called procedural abstraction. Procedural abstraction can be used in order to write several different functions which have a similar structure 2013-02-10 Season 8 PTS Conquest Map! Full build in the Description Below!
