i bet you guys cant get this question its really hard. Can you find a seven digit number which describes itself. The first digit is the number of zeros in the number. The second digit is the number of ones in the number, etc. For example, in the number 21200, there are 2 zeros, 1 one, 2 twos, 0 threes and 0 fours.

3,211,000 - 7-digit-number . 3 - 1st digit that describe the number of zeros it has (which is 3, b/c there are 3 zeros) 2 - 2nd digit that describes the number of ones in the number yeah, 3,211,000 is right !
