Please clarify what you mean with A(10**9)+B(10**9) mod 77777777. Since A(10**9)+B(10**9) < 0 I am not sure of the definition of mod.

I used positive modulo value. -3%5 = 2%5.

A(10**9)+B(10**9) is -infinite, how does it mod 77 777 777??

It's not infinite. It's a very large number. And there are ways to calculate mod of a very large number (example, problem 188 and 282) though I am not saying that knowing how to solve them is required to solve this problem.
