I haven't understood the question.. can you be more clear?

0 1 2 3 4 5 6 7 8
5 2 1 0 0 1 0 0 0

Is the idea that (2*0+1*1+2*2+0*3+0*4)=5 is the number of digits in the second row? So, write down 0 to 9 and then give each a count such that they add upto 9?

521001000

how did u come up with (2*0+1*1+2*2+0*3+0*4)=5 ?? Would you mind explaining me the logic behind it..Thanks in Advance

we can easily generate this, like ....
800000000
710000000
and so on...........
i misunderstood the ques :P ???

Clearly 0th and 1st position has to be greater than 1 in case of length 9 digits.
To accumulate, We need 1 need to be placed for these 2 positive numbers, that make total 4 positions to be filled
0 1 2 3 4 5 6 7 8
d d 0 0 0 0 0 0 0
5 d 0 0 0 1 0 0 0
5 2 1 0 0 1 0 0 0

Dear fellows who posted the solution. Would you also take a little effort to explain the question otherwise how would i appreciate your solution. Please someone take an initiative

cud someone please explain the question and answer clearly

i can't understand this question, we have only 5 numbers,

two 0 one 1 and two 2.

we can make a sequence of size 5 at maximum.
