cut

Cut

x_y

Supported in

K9

The cut primitive partitions the array y before the indices given in array x.

The portion of the array before the first index is ignored.

Indices must be given in ascending order.

 0 4_"feedface"
("feed";"face")

 3 5_"adfdsfsdfa"
("ds"
 "fsdfa")

Repeating indices add empty cuts in that location:

 0 2 4 4 4_"abcde"
("ab"
 "cd"
 ""
 ""
 ,"e")
