Stopword Removal Order Preserved

Problem

Stopword removal filters tokens in place without reordering the remaining terms.

Given tokens and a stopword list, return the tokens not in the stopword set, preserving order.

Hint

Build a set for O(1) membership tests.

case 1

in: [["the","cat","sat"],["the"]]

expected: ["cat","sat"]

case 2

in: [["a","b","c"],["a","c"]]

expected: ["b"]

case 3

in: [["x"],[]]

expected: ["x"]
