Given a non-negative integer or a list of digits, determine in how many ways can the number be formed by concatenating square numbers, which may have leading zeroes.
Examples
input -> output # explanation
164 -> 2 # [16, 4], [1, 64]
101 -> 2 # [1, 01], [1, 0, 1]
100 -> 3 # [100], [1, 00], [1, 0, 0]
1 -> 1 # [1]
0 -> 1 # [0]
164900 -> 9 # [1, 64, 9, 0, 0], [1, 64, 9, 00], [1, 64, 900], [16, 4, 900], [16, 4, 9, 0, 0], [16, 4, 9, 00], [16, 49, 0, 0], [16, 49, 00], [16, 4900]

- Standard Loopholes Apply
