Hi all, I know the way to calculate value of C(n,r) using pascals identity. But i have a different requirement.
C(n,r) = n (n-1) (n-2) ... (n-r+1) / r! Suppose the numerator is such that it cant fit into existing data type. So i remember there is a way to strike off the common factors in numerator and denominator then calculate the result of it. But the logic is not striking to me. Googled but could not find much. So please share the clever way to calculate the above value w/o actually computing the factorials and then making division. My actual requirement is to calculate the value of (n1+n2+....+nk)! / (n1!.n2!.n3!.....nk!) .
