Which formula is used to compute binomial coefficient? C(n,k)= C(n-1,k-1) + C(n-1,k) C(n,k)= C(n-1,k-1) + C(n-1,k-1) C(n,k)= C(n ,k-1) + C(n-1,k) C(n,k)= C(n-1,k) + C(n-2,k) code example

Example: binomial coefficient python

def binomialCoef(n, k): 
    C = [0 for x in range(k+1)]
    C[0] = 1
    for i in range(n+1): 
        for j in range(min(i, k),0,-1):
            C[j] = C[j] + C[j-1]
    return C[k]
