The last three digits of the final number are 109.

The digit zero will no longer be utilized in any counting numbers, according to the Leader of Zip, since it stands for nothing. There can only be counting numbers with 1 digit.
From 1 to 11,
11 is the tenth counting number.
So for the case of first 1000 numbers,
Number of permutations =1000/10 =100
