Very easy:)
just print numbers 1,2,...,n
then n+1,2*n+1,...,m*n+1

Sorry,can you explain why...

Thank you.

because if you take any 2 numbers(a1,a2) from the 2 line and any 2 numbers(b1,b2) from the 3 line,
a1+b1!=a2+b2 and a1+b2!=a2+b1...

or
1, 2, 3, ... n
100, 200, 300, m*100
:)

Can someone explain me why following solution incorrect?
1,2,3,..,n
n, 2*n+1, 3*n+2, .. m*n+m-1

I got WA#1 with it.

Thank you for advance!

You may write random numbers and get AC@)

How?

it's not true. random numbers can't be always true. In fact sometimes random numbers can be equal.in statement is's written that equal numbers should not be. And even if won't be equals is possible to catch WA.
Sorry for bad Englis.:)

cause you have n twice
