[NOI2019 simulation June 29, 2019] combinatorial number (Lucas theorem, digital dp)
Description:
p < = 10 and p is prime, n < = 7, l, R < = 1e18
Explanation:
Lucas theorem:
\(C_{n}^m=C_{n~mod~p}^{m~mod~p}*C_{n/p}^{m/p}\)
If \ (n,m \) is decomposed in the p-base, it is \ (\ prod C {n [i]} ^ {m [i]} \).
For \ (∈ [l,r] \), the restriction is \ (< R \).
Considering the digit dp from the low to the high bit, se ...
