answer is you either chose a bit or you dont
but, when we have multiple of the same bits we get repetition
we need to count how many times that happens


if they were all differente then answer is

a.size() chose x

we need to count repetitions

2^2 + 2^2 + 2^4 == 8 + 16 = 24

2^3 + 2^3 + 2^3 = 8 + 8 + 8 = 16
