I don't know how to solve this problem with constraints A,B,C <= 31; P <= 10^9; T<=1000 and of course C/gcd(A,B,C) >= 200 doesn't true anymore. I need help with this new problem.
The idea that I've used on the original problem can't be used here (that is I iterate over z from 0 to D/C, because the constraint C/gcd(A,B,C) >= 200 shows that C >= 200 and can be deduced that D/C <= D/200 which fits the time limit and sum up the number of solutions to diophantine equation on each iteration).
