**Problem 6:** Compute a closed form for \[\binom{n}{0} - 2\binom{n}{1} + 2^2\binom{n}{2} - 2^3\binom{n}{3} + \cdots + (-1)^n 2^n \binom{n}{n}.\]The expression involves a series of binomial coefficients \(\binom{n}{k}\), where each term is multiplied by powers of 2 with alternating signs. The goal is to find a simplified closed form for this entire expression.
