Hello, can anyone help me?
I pre-calculated sum of terms up to 300 too.
So,
IF (N >= 1 && M <= 300) the answer is the sum of fib[N] until fib[M]
ELSE
I calculated N % 300 (I called NN) and M % 300 (NM)
And My answer is the sum of fib[NN] until fib[300] (Doing this I "complete" the interval)
plus ...
