I didn't see any mod in problem 4(Seedlings) but all of the accepted solutions seem to have used (10^9 + 7) as mod.

My solution seemed right to me.Could this be the reason it failed on bigger tests(Of course for some test cases answer will exceed (10^9 + 7))?

Update Yes, mod(10^9 + 7) was required to pass the problem(checked in practice) although it was not stated in the problem statement.
