Modulus of Combination Number (Fermat's Little Theorem)

Others 2021-02-28 10:16:36 views: null

Assuming the result of Cnk modulo mod, you can use the inverse element + Fermat's little theorem to find it.

When mod is prime number
n/m%mod=(n*m^(mod-2))%mod

When used, it is generally combined with quick power.
