elementary set theory - An explicit bijection between the power set $mathcal P left({mathbb{N}}right)$ and $2^mathbb{N}$ .

I know how to show that these two have the same cardinality and from that there must be a bijection between them.

Can anyone help with an explicit bijection between these sets?
