k - Partition After Truthy Indices
Tags: array , number , boolean , combinatorics
This atom is dyadic, which means it takes two arguments.
y after the truthy indices in
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], ].
