EXAMPLE

(1/10^0)^(1/10^0) =1^1 = 1.000000.. 9-free = 0

(1/10^1)^(1/10^1) =(1/10)^(1/10) = 0.794328.. = 7

(1/10^2)^(1/10^2) =(1/100)^(1/100) = 0.954992.. = 5

PROG

(PARI) zerotozero(n) = { local(x, y, z, v, j); for(x=0, n, y=10^x; v=(1./y)^(1/y); z=Vec(Str(v)); for(j=3, n, if(z[j]<>"9", print1(z[j]", "); break) ) ) }
