A box of pre-cooked food contains N dishes and each dish has 2 properties, its Protein content and its Fat content. We need to select a non-empty subset of these N dishes such that the ratio of total Protein content to total Fat content in these selected subset of dishes is equal to a given target T.

Answer Yes if possible, No otherwise. Constraints: 1<=N<=50 1<=T,Protein_i,Fat_i<=10

------------------------------------------------------ I don't think bitmask would work given that N can be upto 50. Any other solutions to this problem?
