COMMENTS
Leading 0's are not permitted on any of the terms of the sequences of n. None of the terms are allowed to repeat in a given sequence of n.
Note, this sequence is the same as A331472 until n >= 100.
EXAMPLE
For n = 101, the following sequences can be made:
1-term sequences: {101}, {110};
2-term sequences: {10, 1}, {11, 0}, {1, 10}, {0, 11}.
Their sums are 101, 110, 10+1=11, 11+0=11, 1+10=11, and 0+11=11, respectively; the minimum sum is 11, so a(101) = 11.
