Binomial Coefficient
Detailed guide and Python implementation for the 'Binomial Coefficient' problem.
Problem Statement
Write a function binomial_coefficient(n, r) that computes the binomial coefficient nCr. If r > n or r < 0, return 0.
- •0 <= n <= 1000
- •0 <= r <= 1000
Examples
binomial_coefficient(5, 2)
10
5C2 = 5! / (2! * 3!) = 10.
binomial_coefficient(10, 3)
120
10C3 = 10! / (3! * 7!) = 120.
