r - Generating Coin flips using purrr

Question

Now I'm learning how to use purrr package in r, and thinking about how to generate 5 samples of each 1, 2, ..., 99, 100 coin flips. My image is to create a list, that should look like..

[[1]]

[[1]]
[1] 1 0 1 0 0

[[2]]

[[1]]
[1] 1 0 0 0 1

[[2]]
[1] 0 1 0 1 1

[[3]]

[[1]]
[1] 0 1 1 1 0

[[2]]
[1] 1 0 0 0 1

[[3]]
[1] 0 1 1 1 1

..

Can anyone help me make this up?
