Table of n, a(n) for n=1..50.

EXAMPLE

76, 109 and 114 are the only three k such that k + (product of nonzero digits of k) = 118, hence 118 is a term.

PROG

(PARI) {c=3; z=1100; v=vector(z); for(n=1, z+1, k=addpnd(n); if(k<=z, v[k]=v[k]+1)); for(j=1, length(v), if(v[j]==c, print1(j, ", ")))} \\for function addpnd see A096922
