Start with an empty document and cursor position 0. Each command is [operation,argument].

INSERT text inserts at the cursor and moves past it.
LEFT x and RIGHT x move without crossing an edge.
BACKSPACE x removes up to x characters immediately left of the cursor and moves to the deletion start.
DELETE x removes up to x characters immediately right of the cursor without moving it.
PRINT x records characters at indices from cursor-x through cursor+x, inclusive and clipped to the document.

Return recorded strings in print order.

getPrintedStrings(commands: String[][]) → String[]

commands = [["Insert","addthis"],["Print","5"],["Left","4"],["Right","2"],["Backspace","1"],["Delete","1"],["Print","10"]]return = ["dthis","addts"]

The print results are dthis and addts.

commands = [["Insert","abc"],["Left","2"],["Insert","XY"],["Print","3"]]return = ["aXYbc"]

Insertion at cursor one creates aXYbc and the cursor sits after XY.

commands = [["Print","2"]]return = [""]

Printing an empty document records an empty string.
