] | Your problem is that the list `b` needs the array `t` to determine its structure (length). But the array `t` needs the length of the list before it exists:

The imperative version of the algorithm translates directly into a version that doesn't use repeated list indexing or state, just lazy array construction:

] | You won't need to call `array_filter()` or `array_unique()` if you are going to call `array_flip()` -- it will eliminate the duplicates for you because you can't have duplicate keys in the same level of an array.
