Showing a picture without any explanations as to the data type (or, better, without attaching the code so we could see the type of Input and Output) makes it very difficult to suggest an answer.
Input: The Subject seems to suggest this is a binary String, which makes the input an Array of Strings. If this is correct, then (as you should have learned) a reasonable First Step is to take the "Wire" representing the Input data into a For Loop (with its default Indexing Tunnel) to give you a single String to process inside the loop.
String: The expression "Binary String" seems to suggest that each character in the String will be (considered as a character) "0" or "1". Your Problem Statement suggests you need to process each Character in the String and produced an Array of "Binary" data. Look at the String Palette and see if there is anything that suggests converting a String to an Array (of anything).
Binary Data: Without seeing your code, I have no idea how you are representing the "Binary Data" you show on the 2D Array "Output". I see a 0 or a 1 -- is that a String or Integer (signed or unsigned? 8, 16, or 64 bit?), or something else?
Anyway, answering those questions (for yourself) might suggest how you can solve your own problem.
