### Atom - `k`

- Partition After Truthy Indices

Characters: `k`

Tags: `array` , `number` , `boolean` , `combinatorics`

##### Arity: dyadic

This atom is dyadic, which means it takes two arguments.

##### Functionality

Partition `y`

after the truthy indices in `x`

.

##### Details

At each truthy index in `x`

, cut the `y`

(essentially, each truthy index in `x`

will be the last element in a sub-list of the result). If the last element of `y`

is at a truthy index, there will be a trailing empty list. For example, `0,0,1,0,1 k 10R¤`

returns `[[1, 2, 3], [4, 5], [6, 7, 8, 9, 10]]`

and `0,0,1,0,1 k 5R¤`

returns `[[1, 2, 3], [4, 5], []]`
