sort of flipping a bunch of coins generating a function by coin flipping this will require a very large circuit but still gonna nearly a size like to the N over N okay it's another number of inputs to this thing so this is just saying I take a bit zero one and you know I take n of those bits and I output a single bit okay so in fact every function has a circuit of size about to the you know gram okay so this think of it this way so both um I'm flipping two to the N points and I generate some very very long two to the N bit string this
