Gopal D. - "(Like a Rummy Game) There are 3 colors of tiles. Each tile has a number 1-9 on it. So the 27-tile set makes a deck. There are 4 decks. (Total = 108 tiles) Tile Colors = {Red, Black, Green} The tiles could be grouped together in patterns Types of patterns : The three tiles are identical (R2, R2, R2) The three tiles are of same color and sequential (R2, R3, R4). Sequence cannot be overlapping (R8, R9, R1 is not a pattern) Help : Tile Notations - R2 denotes Red tile having num 2 A player"See full answer

Weida H. - "filter function usually exists in some high level programming that adopt FP paradigm. It taks a sequence of items and a predicate function, and returns (conceptually) a subset of the items that satisfy the predicate. Adopt this kind of operation (filter, map, reduce, take, pairwise ...) can help writting cleaner code, and reduce the usage of mutable part in the program, lower the possibility of making human mistake. Take Python for example (although const-ness is not exists in Python), assu"See full answer
