The formula for the binomial coefficients is. ( n k) = n! k! ( n − k)!, so if we want to compute it modulo some prime m > n we get. ( n k) ≡ n! ⋅ ( k!) − 1 ⋅ ( ( n − k)!) − 1 mod m. First we precompute all factorials modulo m up to MAXN! in O ( MAXN) time.

Method 2: (Using Formula) Sum of even indexed binomial coefficient : Proof : We know, (1 + x) n = n C 0 + n C 1 x + n C 2 x 2 + ..... + n C n x n Now put x = -x, we get (1 - x) n = n C 0 - n C 1 x + n C 2 x 2 + ..... + (-1) n n C n x n Now, adding both the above equation, we get, (1 + x) n + (1 - x) n …
WebIn mathematics, the binomial coefficients are the positive integers that occur as coefficients in the binomial theorem.Commonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written ().
