we have 39 numbers from 1- to 39. we divide into A= 19 numbers , and B= 20 numbers. It will be a set of 5 number will be generated by either A or B. Since there is no repeat. The 19 numbers, and 20 numbers are given. Your job is to find if A is generating a set of 5 numbers , which set of 5 it comes out, or b the same. The only fact you have if A is applied , you can use the quantity, or structure of B. Need algorithm how it is done.
