COMMENTS
The number k is left-padded with zeros as necessary for comparison with n.
Clearly, for all n>=0, T(n,0) = 0 and T(n,n) = n.
For all A051885(n), T(A051885(n),k) = k; no other rows have this pattern.
EXAMPLE
T(10,1) = 0 = a(56) as 0<1 in both tens and units positions. Sequence first differs from A002262 here.
T(104,53) = 3 as 3<4, 0<5, and 0<1.
