WebNov 2, 2015 · For large k, we can reduce the work significantly by exploiting two fundamental facts:. If p is a prime, the exponent of p in the prime factorisation of n! is given by (n - s_p(n)) / (p-1), where s_p(n) is the sum of the digits of n in the base p representation (so for p = 2, it's popcount).Thus the exponent of p in the prime factorisation of … WebMar 26, 2024 · Following is the C program to find the permutation and combination of given numbers − #include long factorial(int); long find_ncr(int, int); long find_npr(int, int); int main() { int n, r; long ncr, npr; printf("Enter the value of n and r "); scanf("%d%d",&n,&r); ncr = find_ncr(n, r); npr = find_npr(n, r); printf("%dC%d = %ld
