Create 2 binary strings to represent these occurrences, where in the first string 1 represents the number at that location appeared another time earlier in the array and 0 if not, and in the second is the same but for appearing later in the array.

Example: [1, 2, 3, 2, 1]

Example: [4, 2, 1, 3] k = 2 Answer = [2, 2, 3]
