yes the badness of ranklist problem

#4

Basically, after you create a frequency array, traverse through entire frequency array , until all elements become 0 . You have to take a element which is non zero, subtract its value and then take the value of i from 1 to 7, and then keep on adding the other values, so as to calculate the badness. based on actual and available rank, actual rank is i and available is your freq array values.
