WebThe formula for combination is. n C k = n! k! ( n − k)! Sometimes, the denominator k! ( n − k)! is very large, but we can't modulo it since modulo operations can't be done independently on the denominator. n! k! ( n − k)! mod p ≠ n! mod p k! ( n − k)! mod p. Now I will introduce the modular multiplicative inverse to solve this problem. Web2 hours ago · For example, the factorial of 5 (written as 5!) is 1 x 2 x 3 x 4 x 5, which equals 120. 7! = 1 x 2 x 3 x 4 x 5 x 6 x 7 = 5040. Pseudo Code 1.
