its forty.
how can you do it manually
zero // starts with "z" :P , no luck here
one - ten // nothing
eleven - twenty // nothing
// now every number which is like 21 , 22, 23 cant be the answer as one - nine is already checked
so check 30,40,so on
you get forty
you go till ninety only
as after 100
everything will repeat
till thousand
so you check thousand // nope
// million // nope
and so on ..
as you say smallest -- you can consider negative
-1 -> minus one
minus is not alphabetically spelled so all negative numbers are out of picture
// i hope i did not miss something in between
// also depend on language we write in // for this answer its english
