Find a 10-digit number, such that the leftmost digit equals the number of "1"s in the number, the 2nd equals the number of "2"s, and so on until the 9th digit that equals the number of "9"s and the 10th that equals the number of "0"s.

No it's not.

Number of 1's in the first position is not updated (it says 0 number of 1s).
